I had my last period on the 27th of march and I had sex on the 6th to 11th.because I was ovulating that period of time .but surprisingly I saw my period today which is April 23. What can I do please?
Hello, although the chances of pregnancy increase a lot while ovulating, the chances are never 100%. What I can suggest is, that make sure to calculate the fertile period accurately. Try to have intercourse on all of the days of your fertile window. You can also try using an ovulation kit. In case it still doesn’t work, consult a professional and have checkups done to know what exactly is the problem. All the best!
I started my last period on 23 of March and I ought to have seen April’s period the 20th according to the calculator but I’ve not seen it.
You can get the most accurate result if take a pregnancy test by April 30. The result might be even more accurate if the test is done first in the morning as the urine is far more concentrated at this time.
Last day of my periods was on 1st this month. had sex from 14th to 17th could i be pregnant?
Hello..I had my period on the 10th – 13th of this month,and i started seeing it again on the 22nd of the month. Though I had sex with my boyfriend on the 16th and took pills..what could be the problem?
Hi Rachel, the pills may cause an early period at times, it is not uncommon.
Hi, I wrote here on april 20th i believe… And i just can’t stop thinking that i don’t want to get my period this month It should fall on the 24th which is two more days and I and my husband have been trying. I feel that i put to much thought into it.
Hi Tanya, did you get your period this week? I hope not.
@emily yes i did get on the 24th-28th and then yesterday i was spotting so maybe this month it’ll happen hopefully
Oh, okay Tanya. Yes, all the best then!
Hey, I have a question. Can anybody answer my question please? I got off my cycle on the 8th of April and I had sex on the 12 of April. Is it a possibility that I might be pregnant, I have been feeling weird since than been having the throw up feeling but nothing come up just gagging.
Hi Annette, there is a small possibility yeah. ATB!
I had my menstruation at March 22 ended in March 28. My boyfriend and I had outercourse at March 31. I know this is my safe days. We were grinding naked about 5 minutes, I think. I was really wet, I dont think pre cum was present. He didn’t masturbated the day before it happpened and he peed before we had outercourse. He said he wasnt even close to ejaculation, he didnt ejaculated near my vagina but he ejaculated on my boobs and I showered the day after, cause Im scared that it might go down to my vagina. But I have read several articles that it can’t get me pregnant. I am on a regular 28 day cycle, Im supposed to get my period on April 19 but it didnt come. Im 4 days delayed. Am i pregnant? But, I literally don’t feel anything. Im super stressed that I think I might get pregnant. Please answer. Thankyou.
Hi Kathryn, you probably have got your period by now. But just for the future, no days are safe as such. Yes, the probability of conceiving is low just after your period and just before your period, but the chances are never zero. So use protection to avoid that small chance.
Hi… I normally have 28days cycle but last two months, it has been irregular. Am supposed to see my menstruation on the 30th of March, instead I saw it on the 3rd of April. I had unprotected sex on the 20th _23rd of this April, please is there any likelihood that I will be pregnant?
Hi Blossom, yes there is a chance of pregnancy as it must be close to your ovulation period. ATB!
Hi Steffy I had my last period on March 25th for 6 days. I’m a regular 28 days cycle…Had unprotected sex with my husband almost every day. Expecting my period today but nothing yet. I took a pregnancy test 2 days ago but it was negative. Could I be pregnant or not?
You were fertile from April 06 to 10, 2016. If you had sex on those days then he chances of being pregnant would be high. Wait a few more days to see if your period will come.
I want to be pregnant but my hubby does not want me what do I do
Leave him and fine someone better to have a baby with.
Listen to your hubby and stay quiet
Hi, I’m usually on a 29 days cycle. However, my last menses came in the 14th Mar and it lasted for 2 weeks till the 29th Mar. This is my first time having my period for so many days as usually it will only last about 6 days. My period have not come for the month. May I know when I should be expecting my next period? Thank you!
Hi Vivi, please see a professional. Don’t get alarmed, but menses for 2 weeks is not normal.
Hi. My last menstruation was February 29, 2016. Usually, my mens lasts for 5 days. It’s already April 22 but still, I haven’t have my menstruation yet. Aside from taking pregnancy test, what are the other factors I could consider in determining if I am pregnant?
Hi V, Other signs are sore breasts, Increased need to go washroom, mood swings, tiredness etc. But these all may be due to other reasons also. The only accurate way to know is to take a pregnancy test. Also, take it after 10 days of missing your expected period date for more accuracy. ATB!
I saw my period on 7th of April it stop on 10th of April and I had sex on 16th of April am I free?
In my opinion the 16th is the 9th day of your cycle, depending on how regular your cycle is or how many days, assuming your cycle is 28 days the fertile period is 14th to 16th day. Since you had sex on the 9th day it’s safe. however the sperm, depending on its health, can stay stay alive for 2 to 4 days and if it stays alive till the ovulation period fertilization can still happen but it’s a small chance. a PT can help eliminate the doubt.
Hi my name is Courtney and last Sunday which was April 18th me and my fiancee had unprotected sex. Last month my period started the 24th and ended the 26th. We are not ttc at this point in our lives. Since the 18th I have been feeling very queasy and light headed my nipples are hurting and sometimes tingle I keep cramping very bad but no period. My period due date is two days away but something is not right. When I eat or smells certain things I get sick to my stomach. Now I know I’m not crazy but I need help so please if anyone else has experienced this help me!!!!
If I had sex on the 17 or 18 and my ovulation dates was 20 through 24, can I still be pregnant?
Yes. The risk of getting pregnant is high because your partner’s sperm can live inside your body for at least 72 hours. You can become pregnant just before ovulation as long as one sperm is alive; in essence the sperm could be there waiting for an egg to be released during the ovulation process.
