Hello. I am so baffled over my situation and I am hoping someone will have some advice for me. I am 19 years old and have had my period for 9 years now and it has always been regular. I have never missed a period before. My LMP was about July 17th, 2007 and it is now September 23 and I have not had a period since. No light bleeding, no spotting, nothing at all. My boyfriend and I have unprotected sex (using withdrawl) and I am not on any form of birth control. I took an HPT a week after my first period was missed and it was NEG. I took another one about two days later, it was NEG. I took another one right around the time of my second missed period and it was still NEG. What is going on with me? I am not under any stress. Never had any "female" problems in the past. I thought for sure I was pregnant when I missed my period since I've never missed before. I am urinating more frequently. I am not one to ever get headaches but the past month I am getting headaches quite often. As far as nausea, I really haven't been nausiated recently, but on and off I was feeling sick to my stomach in the past month. I get tired easily. My breasts were really sore back when I was expecting my first missed period, for about a week or two, but they don't really feel sore now. They feel a little heavy but thats about it. I feel bloated all of the time with occasional pressure and/or slight cramping. I also notice my urine is cloudy most of the time if that means anything. (Not a UTI) Is it possible that I can still be pregnant after the 3 negative HPTs?? I have a doctors appt. Oct. 2 with my OB/GYN. Someone please help!! Thank you!!
