Weird cycle don’t know when to test

So… my cycle was kind of weird.

I had a chemical pregnancy last month unfortunately and so did not ovulation test until cycle day 17 knowing that usually my ovulation is cycle day 20. On cycle day 17 I got a 0.55 and that’s it. Then it went back to 0.20, 0.15 and so on. Cycle day 27 still nothing 0.15 that’s it. And then… then I ran out of tests 😭 I wasn’t able to get new ones in time. So now I have no idea when I ovulated?? Cycle day 17 or earlier? Or later than cycle day 27? I don’t know! At all… so here’s my question when do I test? My period was due 2 days ago.. and nothing. Should I take a test? Or wait?

Btw I’ve had chemicals in the past. The first time I ovulated later the next month but the second I ovulated earlier.. so could be either this time 🤷🏻‍♀️
