I had unprotected intercourse on Sept 28th, took Plan B on Sept 30th and began to bleed a bit (not my usual period) on October 2nd. I then had unprotected intercourse on October 12th and have recently been told that I conceived on October 8th and am pregnant. My question is, "Is there any possibility that this pregnancy could be due to having sex on Sept 28th?" Could the Plan B have failed and while my doctor is saying I conceived on October 8th (which is impossible), I really conceived on Sept 28th? Please help...
Kc:confused:

It is always possible. Plan B is not always 100% effective. However, I would venture a guess that you actually got pregnant on October 12. You see, at your stage of pregnancy it is hard to differentiate 4 days. Later an ultrasound will determine a better conception date.

Yes it is possible, I will take it, that the sex was with two different men?
And now you don't know which one?

This is why Plan B is not a method of birth control but an emergancy plan for times when it happened beyond control. For normal birth control there are several methods and more than one should normally be used.

I doubt that if this is two differnet men, you will not be 100 percent sure till the baby is born and there is a DNA test.
