Did I ovulate?

Michele
I had my 2nd mc in a row at 11 weeks w/ d&c on 1/20. 3 day AF started 4 weeks later on 2/18. Now here is this cycle: I have gotten several bfp (5-6 dats worth), now today they are getting lighter. Quantitative test on 2/7 (after multiple positive frer) came back neg. 
After my last mc, I started O sooner and had 25-26 day cycles. So for me to O sooner this time isn't out of the question. 
I took another frer today and it looked lighter. 1st: how did I get so many bfp and neg blood? 2nd: if I was pregnant was it a chemical?
Temp is still up. If it's a short cycle and early O, I should start soon. If it was a regular O, I'm still a weekout! Ugh nothing is making since. Plus: nauseated, cried watching the voice, boobs sore (they are not usually sore before AF). 
Any ideas ladies?!
