CD 5 (AF left this afternoon πŸ‘‹πŸ½πŸ–•πŸ½πŸ˜‚)

Sarah-Jane β€’ TTC 16 monthsπŸ’We did it🀰🏽Sophie born 10/7/18πŸ’•
I've decided to start OPKs from end of AF, I've not really tested this early and I know it's not positive but there's a second line there I would normally see these day 10 onwards until I get my positive. Is this just because hormones from AF or is this usual? πŸ™‚
