I have just gone off lexapro for 5 days....back on it now...but i have missed my period...i have taken 2 preg. tests but both came back negative. no symptoms either that i am. just feel some cramps. id say im about a week and half late. Does this have anything to do with lexapro? Could I be pregnant? I've had protected sex with my boyfriend but condom broke once a month ago...but nothing was in me. please help..whats going on!?
