Hi, If you have not got your period till not, please take a pregnancy test again. All the best!
Hi ani here!
My last period was on 10 Feb and today I had pain in lower tommy
But today 1 drop is coming like period.
What you suggest to me
I got married in last year past 8 Month it was start in December 17,2015
My 1st miscarriage was in jan
What is the issue
Hi Anni, have you got your period by now?
Hi. My period was on February 24, 2016; my ovulation days are 7-11th of March. I had sex the night of the 12th. Is it possible that I could get pregnant? My cycle is 28 days.
Yes, it is possible that you conceived. Good luck!
I had an abortion 7 weeks ago. The pill one. I was bleeding for approx 7 days. Me and my boyfriend had sex after that and I didn’t want to take any risk so took I took a pill. I did 2 – 3 preg tests and it’s negative. But I still haven’t got my periods. What do I do?
Don’t worry about your delayed period – in most instances, a menstrual cycle is expected within 4 to 8 weeks after an abortion.
Hi. I had my Jan period on the 09th of Jan and Feb period on the 11th Feb. I’m still waiting for my March period. I had unprotected sex on the 29th of February. Can I possibly be pregnant?
My period started on 8th to 11th of march 2016 and then had sex on the same day of 11th. Could I be pregnant?
Yes, it is possible but it depends on the number of days in your cycle. Women with a short cycle, for example 21 days, who bleed for 7 days, can ovulate and get pregnant right after their period.
On the other hand, with a regular 28 to 30 days cycle, ovulation typically occurs on the 13th-16th day so the chances of getting pregnant after a period would be low for these ladies. It really depends on your menstrual cycle.
My fertile week was 25-29th Feb 16 and on Friday I got sent home from work due to having tonsilitis and the anti biotic they gave me made me really sick. Could this be a sign I have conceived? I was due on my period yesterday but no signs of that at all just constantly feeling sick tummy ache and I have refused to take the antibiotics. Is it to early to do a hpt?
I have been highly stressed and depressed so bad lately a couple times I got major headaches. I’ve been thinking about a lot. I lost my virginity to my boyfriend on Feb 23. It was VERY quick, he was supposedly a virgin too. He stopped after 4-5 thrusts to get another condom because I think he produced a lot of fluid. Like an inch high of sperm!! He saw I was crying and stopped and comforted me while tearing up too.
A few days after I felt weird in my lower abdomen and have been gassy a lot lately. My chest feels like it has been getting bigger and today I was supposed to get my period, but maybe it’s a day late like last month!!?! I craved salt heavily 4 days after it happened. I’m not on the pill because I promised myself and my parents I wouldn’t do it. He couldn’t keep his stuff in his pants. I hate sex. I’m only 17 he’s 18. WHAT IS THE POSSIBILITY OF BEING PREGNANT?
The chances of you getting pregnant depend on the number of days in your menstrual cycle and the first day of your last period. Can you confirm this information?
If you were not ovulating when you had sex then the chances of you being pregnant would be low. On the other hand, if you were ovulating or fertile at that time then the chances would be high. Also, if you conceived at that time the symptoms would not be experienced so soon.
My period is due March 16th but my period came 5 days early. My fertile days was Feb 28 – March 4th. I had unprotected sex March 2 and March 4. Could I still become pregnant and miss my April period that’s due on the 13th?
Hi, I haven’t had a period since Jan. 11 (first day of last period). I been to an Ob-Gyn, taken a blood test and 4 home tests, all negative. What should I do?
You now need to have your doctor determine if you have any issues with your hormones. You need to determine why your period is delayed since you’re not pregnant.
No I did not have have that no egg white mucus at all, today I am 7dpo and feel normal from 4-6 dpo I was very tired taking two naps a day and had very watery and sticky discharge. At 5 dpo I had cramps on and off and a sharp pinching pain on my left ovary for about a minute or so. Had a very bad sore throat at 5 and 6 dpo. All my symptoms are gone today . I did a opk test and had a faintish second line. Don’t know if I could be pregnant or what I hope I am !
Carmen, I think you should try taking a pregnancy test to be sure. All the best!
Hi. I am a 22-year-old and I have recently noticed that I skip a month after every period, i.e I had my period on the 18 Nov 2015, missed December then had my next one on 6th Jan 2016, then again missed Feb I started today 12 March again. The dates are also changing a lot I can’t keep up anymore and I don’t even know when to expect my period.
Hi help me out !!! I had a bad period DEC.29 .15 took provera pill for 5 days the bleeding never stopped tho and then after that I had intercourse Jan .15th it shouldn’t of happened but I was irresponsible for messing around like that and tested on Feb.1.2016 negative then got a period the next day Feb.2.16 lasted till the 6th and after that I tested on the 6th and 7th again negative pregnancy tests , so I had sex with my boyfriend from Feb .8.2016 -Feb.23.2016 and never got a period march I tested on the march.8th and got a positive pregnancy test twice my question is it possible to have gotten pregnant Jan 15th or is it more likely that I’m pregnant by my boyfriend who I had sex with after that period on the 2nd we did it from 8th to 23rd ?
Hi Brenda, if you are 100% sure that from Feb 2 to Feb 6, your bleeding was due to period only and not any other kind of bleeding, then the most chances are that the pregnancy is because of intercourse in between 8th to 23rd Feb.
Ann:I’m 36years and for about 2years I have never had my period and always have abdominal pain when I’m due for the period and I am trying for a baby
Hi Ann, I would see a professional for it.
Hi there, just a quick question. I had my last period on the 8th of February and it lasted 5days. In between the period till now I have had unprotected sex . I am yet to get my period for the month of March. Is there a possibility I am pregnant. Today is the 12th and still no sign of my period.
If you had sex during your ovulation period then you’re at risk of becoming pregnant. Continue to monitor your body to see if you conceived.
Hey im have problems. My last period was feb 9,2016 and i was suppose to get my period march 7,2016 and i still have received my period. Me an my boyfriend had iendfeb 19-21 then 23-25.

Hi Maria, I can understand your fear, but there is no better way to make sure you are not pregnant. So please do take a pregnancy test. All the best!
