Is it normal for a period which start on 30 of March to extend to April??
Hi Gudness, Considering there are 31 days in March and that would only be a 2 day cycle, yes it’s completely normal for it to extend into the next month. Just because the calendar date changes doesn’t mean your period will adhere to it.
Hello, I started my periods on the 29/3/2019 and finished on the 1/4/2019 the same on the 1/4/2019, I had unprotected sex, on the 28/4/2019 I was having a pain at the right side of my tummy to the down of my tummy and my back too today on the 30/4/2019 am seeing someone light bleeding.
Hi Evelyn, it could be your period honestly. With having sex on the last day of your period with what appears to be 29 day cycle, you would not have been ovulating at that time. The pain you felt could have been PMS. I would recommend waiting a few days and taking a pregnancy test if you don’t experience what you consider to be a normal period.
Hi
I got my period on the 27 March and ended the 30 March. I’m supposed to get my period the 24 of April its the 29 of April. Should I get tested?
Hi Rechel, Sorry for the late response. If you haven’t gotten your period at this point than yes I would recommend a pregnancy test.
I saw my period on 3rd of April.. But had sex on 21st of April.. Now is 27th april.. Haven’t seen my period yet.. Please am I safe?
Hi Bless, Based on a 28 day cycle you would be looking at your period the 1st of May. So unless you have a shorter cycle you haven’t reached the day yet. If you haven’t gotten your period yet I would take a pregnancy test. However your ovulation period is the 13th to the 17th. SO you most likely should still be anticipating (or have had at this point) your period. If as of this date you haven’t gotten it, take a test.
My period was on 3 march, and that much late and now April 27. What happened? I tested again and the result was negative. Please answer what should I do?
Hi Dina, so are you saying you haven’t had a period since March 3rd? Consider any major changes that have happened in your life. That could be the cause, however if you still haven’t gotten your period (and if you aren’t of menopausal age, or even if you are), make an appointment with your doctor as they can run blood work and see what is going on.
I have a question my period came on April 8th and came off April 14th or 15th had unprotected sex April 22nd an the next day I’m spotting pink in it’s only April 26 right now why am I spotting?? When should I take a test
Hi Quinisha, Spotting could be ovulation bleeding at this point. However, you should anticipate your period (or have gotten it already) somewhere around the 6th of May. If you haven’t at this point I would take a pregnancy test as the 22nd would have been the last day of your ovulation period.
Hi I got my period on 15th and finished on 18 th when I can get pregnant ? I want to know the dates.
Hi Jass, based on a 28 day cycle you would have been fertile from April 25th to the 29th. Since we have already passed that timeframe you should be anticipating your next period from roughly the 13th to the 16th of May and then your next ovulation period and most fertile time period would be from the 23rd to the 27th of May. Good luck!
I had my period on 24 of march that lasted for 3 days and on the 5th day I had unprotected sex. It flowed again and stopped. I made love for two weeks and I took postinor 2 and have not seen my Period.
Hi Zainab, if I understand you correctly you took emergency contraception. Because it’s a large surge of hormones it can affect your next period. For some it comes later and some earlier. However, if you didn’t take it within the recommended timeframe (at most 72 hours) after unprotected sex (and the longer you wait the less effective it can be) you could still have gotten pregnant. It also does not protect you for the rest of the month, just that session so to speak. Take a pregnancy test at this point if you have not gotten your period.
Hello I started my period on 26 of march
2019 with no sex and to it has start again what is the problem I don’t understand twice in month
Hi Stix, There isn’t enough information in here for anything to be said. Twice in a month is always possible, especially when you have your period early in the month then if you have a cycle less than 30 days you would inevitably see it twice that month. Hopefully that helps.
My period started on 25th March 2019 and lasted for 5 days. I had sex on 2nd April 2019 but we used protection. My cycle usually is of 28 days. So is there any chances that I might have conceived.
Hi Aliah, the 2nd of April would have been 2 days prior to your ovulation timeframe, however if you were protected there shouldn’t have been any worry (although failure of whatever protection you are using is always possible).
May last period starts last April 8, 2019. We had an unsafe sex with my husband today April 21, 2019. Is there a possibility that I will be pregnant? How many percent of chances? I have a normal cycle. I am worried because of my age. I am now 41.
Hi Ann, well the 21st would have been during your ovulation timeframe, so yes it’s quite possible that you got pregnant during that time period. If you haven’t seen your period at this point I would recommend a pregnancy test if you have’t done so already.
My wife had her period in march 3-6 and also had another period from march 30 to April first,is it possible for her to have another period in this same April?
Hi Cyrus, Sorry for the late response however yes it is possible. If her cycle isn’t 30 days and she has it at the beginning of the month yes having it a second time is completely normal.
My last period was march 17 and lasted 5 days ended on march 22 and my cycle last 30 days my nipples and boobs hurt and ive been eating syrup with my french toast i hate syrup with a passion could i possible be pregnant
Hi Erica, did you have unprotected sex during your ovulation window? If so then yes it’s quite possible. However food cravings can be for a lot of reasons. I would recommend a pregnancy test if you haven’t taken one and haven’t gotten your period. That being said, March 22nd would not have been anywhere near when you should have gotten your next period. Now if you have’t gotten as of when you posted this on April 19th, then yes take a test.
My last period was on 21st March and I had sex on 10th of April till now I have not seen my period what’s going on please.
Hi there, have you taken a pregnancy test? If not that should be your first route to go. Especially at the time of my response here.
I got my period in feb from 1st to 5th, we also had sex during my most fertile time that month. In March I did get my period from 10th to 13th. This month that’s April I still haven’t got my periods yet. I should have come on the 7th or the 8th and ended by the 11th of April maximum. I have no sign of period at all except for 2 days last week where I did see very lil brownish blood but just about 1% only when I use a tissue to wipe and check. Could someone tell me what’s happening!??? I am really tensed and confused. I’d be glad if I’m pregnant but if I’m not then what’s happening. This is quite irritating. Please help!
Hi Nisha, take a pregnancy test. That is the best advice I have for you at this point. Good Luck!
Please I am having serious cramps after I menstruated. Please what can the cause be? thanks
Hi Jane, That could just be how your body handles your period honestly. Cramping is something that a lot of women deal with especially with PMS. The fact that it is after your period could just be your bodies way of clearing itself out. If it doesn’t get relieved by general pain medications then I would recommend speaking with your doctor as they can run tests and see if there is something else going on that is causing the pain (there are plenty of conditions that can cause cramping and should be checked out). Good Luck!
