Hello. Me and my girlfriend had sex without a condom on saturday night.. Im pretty sure like most guys i did pre-cum and now im getting scared. 2 days after we had sex, she started complaining about feeling sick. Shes never been pregnant before so could the pregnancy symptoms possibly show 2 days after we had sex? Could her feeling sick just be a coinsidence?

im almost certain that u do not get any signs and symptoms that early.
Did u tell her straight away what you did, because she could have taken emergency contraception.
in order for her to find out shes pregnant, take a test after 1-2 weeks. its best to do a early morning sample as the urine then is more acurate.
And hopefully next time make sure someone is using some protection.

no thats not possible. the reason i know this is because i was pregnant a few months ago but misscarriaged. but anyways, after my period was 2 weeks late i went to my doctor and told her the situation and she gave me a pregnancy test there and then and it came up negative so she gave me two to take home with me and she told me it takes a few weeks and then done the second 1 it also came up negative but then the 4th week it came up possitive so nooo your girlfriend is not pregnant

She wouldn't be able to feel any symptoms that early, it would take a few weeks at the earliest I believe... if its under 72 hours since you've had sex she can still take emergency birth control (morning after pill)...
