Period due 5th Feb

AF is due in 7 days.. we had unprotected sex during fertile window and day of ovulation and after ovulation.

This is our first month trying for baby number 2 so we’re not getting our hopes up. But we did get pregnant the first month trying on our first child so I’m praying the same happens again!

When is the earliest I can test? Or shall I just wait until Af is due?
