Chances are pretty good that she was ovulating. A woman normally ovulates 12- 16 days before her next expected period. If your GF is on a 28 day cycle, her next period should fall on May 25. 12- 16 days before that would make May 9- May 13 her fertile/ ovulation days. If your GF has a 32 day cycle, her next expected period would be on May 29. 12- 16 days before that would make May 13- May 17 her fertile/ ovulation days.
Pregnancy is most likely if intercourse occurs anywhere from 3 days before ovulation until 2-3 days after ovulation.

very HIGH!!

her breasts have been real swollen and sore the last few days...but that wouldnt happen this fast would it? we only had sex on tuesday..

?

We can't give you a definate answer.

The only sure way to know if she is pregnant is for her to take a pregnancy test.

If the unprotected sex occurred on Tuesday...she should wait until she misses her period and then test..

could she really have swollen/tender breasts a few days after conception?

if she is worrying about being pregnant it could be this that's causing the tnederness. Your best bet is to wait until her period and if doesn't arrive when it should then she should do a test. You're probably worrying yourself sick right now but don't, you won't know until her period due date is here so it's best just to get on with things until then.

like the above poster said I wouldn't fret about , although the chances are up there. The only way you can tell is to wait until her period is supposed to come and to do a test, or make a doctors appointment. So until just be your normal selves although I know its not easy. Hang in there!

she is now a few days late on her period...no good!

shes pregnant!
