Several High fertility readings

So I thought I had my BFP last month as I had several positive tests. But about 4 days after my period was due I started bleeding. So I'm not sure if it was a chemical pregnancy or a miscarriage. This month I have been using an ovulation kit like I have in the past. Normally, I get a few lows, then maybe 1 or 2 highs and then I get a peak reading. Well after around 4 lows, I got a high, and now I've had 5 or 6 of those and no peak reading. Any clues as to what's going on? I thought maybe I wouldn't ovulate this month since the episode last month and my body needed to get back to normal? but not sure.
