So confused..

Okay so I had a miscarriage last month on Thanksgiving...my question is how long do I wait for my period to start if I didn't get pregnant this month? I just logged it into glow as a period and it says it should start in 10 days but I'm not sure if that's right or not..

Btw my levels were at 0 the Monday after and doc said it was ok to try agian righy away
