Posted on Mon, 26 May 2014
Question: If I had my period on march 10th, and had unprotected sex, every weekend after, with the last encounter being march 31rst in which he didn't ejaculate and I took the morning after pill 5 days later. Then on April 5th, i took 3 at home pregnancy tests in which they were all positive. Then on April 18th, I had a dating ultrasound which dated me at 5 weeks 4 days. What is likelihood that it was the march 31rst encounter in which I got pregnant?

Brief Answer:
Chances are less.

Detailed Answer:
Hello,
Thanks for trusting us with your health concern.
On April 18th if the dating by ultrasound was 5 weeks 4 days then your date of conception is 25th march +/_ 5 days (Chances of error) . The chances of conception by 31st march episode are less but cannot be ruled out completely.
Taking an I-pill 5 days after unprotected sex is of no use. It has a high rate of failure if taken after 72 hours.
Please feel free to discuss further. I will be glad to answer the follow up queries that you have.
Wishing you good health.
Regards.

I must have already been pregnant on the 31rst of march, bc if the 31rst was the only act of intercourse I wouldn't have had a positive test just 5 days later.

Brief Answer:
Yes.

Detailed Answer:
Hello.
Thanks for writing again.
Yes it takes 7-10 days for the urine pregnancy test to become positive after conception. That makes the chances of conception on 31st less likely. Ultrasound is a surer way for dating the pregnancy. At 5-6 weeks the calculation can vary by 5 days.
The chances of conception after 30th march are remote. Please do not worry.
Hope my answer is helpful.
Do accept my answer in case there are no further queries.

So your final answer would be you think I was pregnant before the 31rst of march?!!

Bc if march 31rst was the only intercourse I wouldn't have had a positive test just 5 days after.

Thank you.
