I am 6 days post coitus, and this morning I felt nauseas and yesterday and today my boobs are so sore my DS can't even lay on them. AF is not due for another 9 days. When should I test?? I did not have any symptoms with my son I just tested on the day I was suppose to get my period out of curiosity. 2 of my really good friends are pregnant and I have baby fever so bad please help? :/
