Okay

If you had a normal period on the 13th of January, then you cannot be pregnant from sexual intercourse prior to the period.

Intercourse on January 18th will not cause a pregnancy either since the follicles in the ovaries at that time are not mature enough to get fertilized.

Since ovulation occurs approximately 14 days after a menstrual period, you would have ovulated at around the 27-29th January. Intercourse on the 31st January will be on your fertile period. The sexual intercourse on the 31st has caused this pregnancy.

Since the pregnancy is dated from the last menstrual period, it is now 5 weeks from the 13th of January.

I hope this helps.

After intercourse on the 31st I took a morning after pill on February 1st my ovulation was February 2nd and I had intercourse February 3rd through February 4th will that make a difference
Customer reply replied 4 months ago
When I took the Plan B pill did that cancel out the pregnancy on the 31st

If you are sure that you ovulated on the 2nd february, then yes, intercourse on the 3-4th february could also have cuased the pregnancy.

Ipills have only a 89% success rate - so you can still be pregnant.

If you ovulated on the 2nd feb, then sexual intercourse either on the 31st Jan or 3rd feb would have caused the pregnancy, although that on the 3rd feb is more likely.

I hope this helps.

how will I know for sure if it was the 31st or my sexual intercourse from the 3rd and 4th

I am afraid that you cannot be sure without a paternity test.

Another newer test which tests for fetal DNA in the mother's blood can also be done which can be used to test for the paternity. You will need to talk to your doctor about this test.

I hope this helps.

An ultrasound wouldn't help

No, an ultrasound cannot identify between very close dates, since it always has an error margin of about plus/minis 3 days at this time of pregnancy.

I hope this helps.
