All messed up hormons!

I hope someone can give me some advise concerning this. I've experienced a mc on 2/01. Ever since my hormons are going crazy. First time after mc i had a heavy period for 6 days, 2nd time very light and only 4 days. Also between the 2nd and 3rd period i had 5 days of ligh spotting in a row. Now the 3rd time i was 7 days late, i was so happy. I did 2 tests, both negative. And on day 8 my period was there to give me a good back to reality call. My period ended on Saturday. It was a light period of only 4 days but with lots of pain. Today I experienced again some spotting .... Also Glow is confused i think because it's saying that Sunday, Monday and Today are my peek days for getting pregnant ... I'm lost and confused ...
