For about a week and a half now my breast have been very sore and my nipples even hurt. And I never wake up Feeling sick, ever. We've been trying to conceive for bout 5 months now. And for 5 days now I've been feeling nauseous in the morning. My boyfriend and I had unprotected sex 3 weeks ago today and it was during my fertile window. Is there a possibility I am pregnant and also when is the earliest to take a pregnancy test?
