I had sex almost a month a go well.. It will be a month in 3 days and I've missed my period 4 days now, BUT he didn't ejaculate at all, is there a chance I am pregnant? I also take Carbatrol, Prozac and Trazadone so I don't know if it's the medication holding back my period or the possibility of me being preggers? Please answer... I am on pins and needles...
