OPK almost positive after having a miscarriage!

Tawny
I wasn't sure if I wanted to do OPK after having a miscarriage 4/28, (Dr cleared us to try again immediately as I was only about 4 weeks & few days along & passed it naturally). Today's test is the darkest it's been over the last few days. My husband had a fever last night and achy with sore throat today. Hoping I can convince him to still BD if he's up for it the next few days 😁
