When should I test if I don't know when AF is due?

I had a miscarriage about a month ago and haven't had a period yet. Last Wednesday is when I think I ovulated though. Ewcm, sore breasts, high sex drive so of course we went with it 🤗 but I'm not sure how long I should wait to take a pregnancy test
Also: my doctor already gave me the thumbs up to start trying again, as I had an early miscarriage and I did not need surgery to complete it.
