I’ve got positive tests 4 days early this month, I tested yesterday and it was still pretty light, then tested this morning to get a very close positive, we BD this evening and I’ve just tested and it’s a strong positive, I thought I was starting my fertile week as I normally don’t O until CD18/19 I’m CD 15 today, are my chances good? Considering I’ve only had sex today then got a positive tonight? Il probably O tomorrow 🤷🏻‍♀️ what has your experiences been
