Hi, I had my period on the 5th of March and ended last on the 9th, but I had sex on the 14th of March. Now I have tender breasts which I did a pregnancy test which turned out to be negative. So what do I do now?
It is likely that you did not conceive but you need to wait and see if your period will come. A pregnancy test can be taken at that time.
I recommend you see a doctor

On the 4th last day of my abnormal period , my husband and i got intimate .. and now I cpunted my 21 days for the next cylce and I see I am a week late .. is that normal or cud I be pregnant ?
Hi Thasmera, do you always get regular periods otherwise? Irregular periods are very common and with change in life, even women with regular cycle otherwise, experience those. For now, as it is 12th May today, if you have not gotten your period already, please take a test.
My last menstruation is march 5 and he only touched me 1 time at march 26. can I be pregnant?
If he just touch you then no
I had sex on 15th April and my ovulation started from 16th April, do I stand a chance of pregnancy?
yes, because you had sex during your fertile window. please read this page for more info
Hey, I had my period on the March 29 and ended on the 31st of March and my menstrual cycle is 31 days.I had a pregnancy test a few days ago which was negative but I also have period symptoms; break out, cramps and tender breasts.
I had my period on march 5th and also March within 25-30th and that has never happened to me – two periods in one month. I haven’t gotten it in April and today is April 27th still no period. Can I please get some advice? My pregnancy test was negative.
It is possible to have two cycles in a month. You can take the test but ensure that you consult your doctor as well.
My last menstrual cycle as March 20, 2016, I haven’t had any symptoms of my period. I was supposed to come in April and it didn’t show. Today makes a week that I haven’t had a period and this month is almost over.
You need to take a pregnancy test now to determine if you’re really pregnant.
Hi, I want to know, we had sex on the 14th of March so she missed her period on March 28 means that she’s pregnant or she was already pregnant before I slept with her?
The answer to this question depends on the number of days in her menstrual cycle and if she was ovulating when you had sex. Can you confirm the date of her last period?
OK, THE LAST TIME I HAD SEX WAS JANUARY 1ST. I HAD A PERIOD IN JANUARY AS WELL AS FEBUARY, AS WELL AS IN MARCH. HERE IT IS APRIL AND I HAVENT SEEN MY PERIOD. I TOOK A TEST TODAY 4/26/2016 AND IT WAS NEGATIVE. COULD I STILL BE PREGNANT OR COULD IT BE STRESS? I STARTED A NEW JOB LATE MARCH AND I LOST A CLOSE FRIEND LAST WEEK. WHAT COULD BE THE ISSUE
Hi Nancy, sorry to hear about your friend. Yes, it can be stress. It definitely cannot be pregnancy. Wait for the next month and if you still don’t get normal period, then consult a professional. In case you are taking any medications, that might be the reason too.
hi. I am Pooja. i had my menses on 16th march. it lasted for 4 days. I had unprotected sex on 4th April and i took an i-pill on the same day at night. Now i was supposed to get my next menses on 16 april but I have not got my menses yet and it is already 26th april. Is there any chance of my getting pregnant? Please reply.
Hi Pooja, i-pill may sometimes delay the period, so it’s probably that. But do take a pregnancy test to make sure you are not pregnant. ATB!
I had sex 9 days after my period which was on the14th of april which was my period but it lasts 4- 5 days and had sex on the 22 of april which was 9 days after my period 3 days after which was the 25th of april I started seeing clear mucus discharge in my under wear I just looked this morning and its now a light yellow can some please tell me what it means as me and my partner of 3 years are trying to conceive for a baby
Hi Sharlean, light yellow discharge is often a sign of ovulation and by your date too it can be your ovulation period. In case it had a foul smell, I think you should consult a doctor. Sometimes it can indicate an infection too. ATB!
Hi, I’ve had sex on March 31 and I got my period on April 22. So my question is, could I be pregnant or not? Please help me.
It is highly likely that you’re not pregnant.

Hi Joanna, Have you got your period by now? As you took emergency pills, conceiving has a very low chance.
Hi, so I have no idea what is going on. I usually start my period on the 20th to 28th but last month I started 3 days late and only had it for 3 days so march 23 to march 26th. I took a pregnancy test around april 15. It was negative and then i started my period on april 23 again. Can anyone help me?
Hi Alexandria, this is one of the changes most women experience during life, it’s nothing to be worry about. I don’t think pregnancy is playing any role here. It’s just natural.
Hi I had my period last March 7, 2016 up to March 14. Then after 21 days I got my period again March 27,2016. It was my first time to had a menstruation after 21 days. I had one unprotected sex last April 16, 2016. I usually had my periods 28-31 days.. and it’s the 29th day today I still never had. I tested for pregnancy test since the day I had sex and today..it takes me 5 pregnancy test from April 20 up to now and it says negative. IS it still possible that I got pregnant? Pls help.thank you
Hi Jemma, First, pregnancy tests should be taken 10 days after you miss your expected period date, otherwise accuracy may be less. Then, going by 28-31 days, your period should be on 25th April, so probably you have got your period by must now. If not, then take a pregnancy test after 2 days from now. ATB!
Hello, I had sex April 1-5th. My last period was March 26th. Could I be pregnant?
