I have always had a very regular 30 day cycle. For the past several months, my period has always started on the 10th. January was my last period. It was very normal. About 3 days before I get my period, I always have very strong signals that let me know it's coming, i.e breast tenderness, irritability. I noticed this month (February) that I didn't get any signals before my period, and then, my period didn't start. I had some very mild spotting on the 12th, 13th, and 14th and that was it. I have taken 3 hpts, all of which have said negative. I looked at the calendar, and my husband and I had sex several times while I was ovulating. I have almost every single early pregnancy symptom (Nausea, Heartburn, Gas, Fatigue, Headaches, Uterine Pressure). My husband and I have talked about the situation, and we are both very excited about the possibility of me being pregnant. I am almost positive I am, but why won't the HPT show a positive result. We don't have insurance right now, but I will be able to receive Medicaid if I am pregnant. Can someone please help and lend some advice on what I can do?
