Had sex a wk before period and got a positive pregnancy test 2 weeks after. Is that possible? Or could pregnancy hav happen before that intercourse?

Maybe. Maybe not.: If already pregnant, that would mean the "period" was not a real menstrual period, because having a real menstrual period clears out the uterus... So having a real menstrual period means not pregnant at that time. ...Read more

Can implantation occur a little less than 48 hours after sex? Positive pregnancy test less than 48 hrs after intercourse as well.

Anatomy : Nope. Absolutely not. First: the sperm have to swim through the cervix, through the uterus, out the fallopian tube and find an ovulated egg. This takes more than 48 hours. Second an impregnated egg does not have any connection to the mothers body for over one week after impregnation and even then does not produce enough hormone for the mother's blood to be carrying it. It is impossible to test. ...Read more

So is it possible to have a positive pregnancy test from just after five days of one intercourse or did it have to happen prior?

So is it possible to have a positive pregnancy test from just after five days of one intercourse or did it have to happen prior?

If ONE intercourse..: It makes no difference (doesn't matter) when the test turns positive if there was only one intercourse. With a positive preg. Test and one intercourse, it happened... Regardless if whether it was 1 day, 5 days, or 15 days after that one intercourse, the positive test happened. If there was more than 1 intercourse, then look earlier, as a preg. Test almost always takes over 5 days to be positive. ...Read more

But, as with anything in this wild and wacky world, not impossible. ...Read more
