Hi there click here to find out when your next period should start.
I had my period on 30 March then had sex on 3rd April and my boyfriend released inside but I took morning after to my surprise I had my period in the same month on 10april. I had sex again on 3rd May and fourth May that was on Thursday and Friday but I took the morning after on Saturday. I know this month isn’t over yet but I’m very worried today is 21 may I did a pregnancy test a week ago it came back negative .
Hello Tisa, the test was negative, therefore you are not pregnant.
I was supposed to get my periods on 31st April but I didn’t get it and I had sex with my boyfriend on 6th May and until now I’m not having my periods. Is there is a possibility of getting pregnant ??
Please help me out I’m really scared
Hi Riya, Since we don’t know when your last period was, I wouldn’t be able to give you a straight answer. Your best bet would be to take a pregnancy test. Other than that consider that your period could be late due to medications, stress, weight changes, travel, or illness as well.
I have menstruation last march 27 and ends on March 31, but i have sex wth my boyfriend last april 7 without a condom. And i’m so stressed after that day happened to us, and until now im waiting but not yet. Its may 13 but i tried pregnancy test but its negative, im so stressed about this issues.
Hi Angel, April 7th would have been at the beginning of your ovulation period, so it’s quite possible that you are pregnant. IN the future you can always consider emergency birth control within 72 hours to prevent pregnancy. However, with that being said you should take another pregnancy test. If negative and you still haven’t gotten your period within a week or so I would make an appointment with your doctor. They can do a blood test or determine if everything else is okay as well.
My last period 25 April. l had unprotected sex last 2 or 3 days. l have nausea. am pregnant or not
Hi Simi, I don’t know if you are referring to the beginning or the end of your period being the 25th of April. Regardless you wound’t be in the fertility window. Nausea also wouldn’t show up this quickly so that’s likely unrelated.
Hi, please I saw my period on 16 may, when next will I be expecting it again?
Hi Precious, we haven’t hit the 16th of May yet so I am a bit confused.
I started periods on 3rd April and expecting to be on period on 1 May but till today there is nothing. I never had unprotected sex, I can feel the signs of periods but there is no drop
Hi Susi, if your period isn’t regular yet (I don’t know your age) but it could be that your cycle has not fully found it’s cycle yet. However, anything could be the reason from stress, weight loss/gain, illness, medications, etc. If you have’t had sex then you aren’t worried about pregnancy.
hiya I had my last period on the 3rd April and now it is the 5TH of May what are the possible reasons that I may not have strated as I am always on time for my periods and have never been late ?
Hi Ikra, could be a few reasons, pregnancy, illness, medications, travel, etc. The body will change and possibly delay your period if there is a lot going on. If it’s possible that it could be pregnancy I would recommend a pregnancy test.
My girlfriend had her last period beginning on 10th April, we later had unprotected sex on 27th April.could she get pregnant?
Hi Mark, while based on a 28 day cycle her fertile period was between April 20th through the 24th, it could be earlier or later. And if she hasn’t gotten her period as of this response it’s a large possibility. If she still hasn’t seen her period, get a pregnancy test.
hiya there. I started my last period on the 3 April 2019 and now it’s the 5th of May and my period has not still come. Is there any chance I could be pregnant?
Hi Kirsty, it’s quite possible as you would at this point be two days late based on a 28 day cycle, however multiple things could be the reasons for. delayed period such as illness, medication change, weight changes, etc. However, I would recommend taking a pregnancy test.
Hi, my last period was march 29th and I had unprotected sex April 10th and April 13th and still haven’t gotten my period. What does this mean?
Hi Jessica, you should be taking a pregnancy test at this point to determine if you are pregnant or not. You are nearly a week past your anticipated period so I would do that first in order to determine what it means.
I started my period on the 22nd of April and I had an unprotected sex last day of my period and now have started another period on 2nd of May.is it okay??
Hi Funmi, I would say that what you are experiencing right now is not a period possible ovulation bleeding. Based on a 28 day cycle you would be ovulating between the 2nd and the 6th of May so this is most likely what you are currently dealing with instead of an actual period.
My girlfriend started her period on 22nd April and I expect to have unprotected sex on 9th may, will she get pregnant?
Hi Mugadu, While it’s not during her ovulation period according to a 28 day cycle, anything is possible. She could ovulate sooner or later. If you aren’t looking to start a family with her at this current time I would recommend protection. While there are women who are extremely regular, not all women are. There are plenty of option available to you both for preventing pregnancy, I would look into them.
Please what can cause irregular periods. Before I used to have my period for 5 days and now since January it is 3 days.
Hi Ademide, there are a lot of reasons that you could be experiencing a change in period. Now if you are just starting out with your period it could still be working into it’s regular pattern. Also consider if you have had stress in your life, change in medications (especially new birth control), traveling, medications, illness, drastic weight changes, etc. Keep track of it and see where it goes. If any of these things sound like you then just know that it could change back to your 5 days, however this could be your new normal.
