Weird ovulation after miscarriage??

I had a miscarriage about a month ago with my first baby - I was very early, around 6 weeks. I’m now finally starting to spot/maybe get my period but it’s VERY light! I take it as a good sign because that means I’ll maybe be able to start tracking my ovulation and try for a baby again!

But, for the past week my ovulation tests have been consistently measuring me at 0.29-0.34. Is that odd? Shouldn’t it be fluctuating more day to day?

Maybe it’s just me overthinking/over worrying…
