still no af.... having symptoms bloating... just wondering what the hell is going on. my last period was in November. mind you I'm irregular In December only light pink discharge on the 8th and then two days later light brown when I wiped but that was all. this month i had some cramping but at never showed.... I've taken a few cheapies already and all read neg. this morning I took FIRST Response but idk if it's evap or negative.... with all my pregnancies (3 )/ 2 living I've missed a month but the next month tested positive. can I still be pregnant but it's not showing????? SOMEONE PLEASE COMMENT THANK YOU??? HAS ANY ONE EXPERIENCED THIS AND ENDED UP BEING PREGNANT pic in comments
