What is wrong with my body

So about 60 days ago I started testing 2 weeks before my period because I thought I may be pregnant. I got a some faint positives but then I also got negatives. I missed my first period June 19. Soon after that I went to my OBGYN and had a blood test which was also negative. Since then I've missed 2 periods so 3 missed periods in all. This would be my second child so I know what movement feels like. For the past week or 2 I've felt flutters and I know I'm not making this up!! Tonight I was looking down and I felt a small kick. I immediately looked at my stomach and I SAW IT!!! I know 10000000% what I saw. I don't know what's going on with my body and I need some opinions. I have an app and if I were to be pregnant I would be a little over 10 weeks! Please someone talk to me about this!
