what the hell...

So here's the thing, I haven't had a period since January. I took a PG test March 3rd it was faint positive. I took another the next morning and it was negative. continuing to take tests after that and they are all negative. I have one daughter already and right now I would be about 12 weeks (give or take ish) and I remember at 14 weeks with my first I felt flutters. Well ladies, that's what I felt yesterday and today. I go in Monday for a blood test and I'm scared. not about being pregnant

because im praying I am (hubby and I want our second) but nervous that it's something more serious. I'm not even sure why I wouldn't be because I'm always on time but all my tests since March 3rd are negative. ALSO since I wasn't getting anymore positives I was put on provera for ten days and 14 days after I stopped taking it and still to this day haven't had a period. STILL neg tests. anybody else end up being pregnant and couldn't get a positive home test? if not anybody have something similar happen and find out something else was wrong? I'm going crazy! no preg symptoms other than super emotional but with my daughter I never had a single symptom with just late period. HELP!
