So for the most part my periods are pretty regular, my husband and i are trying to have a baby’s first started in June I didn’t use ovulation tests we just had unprotected sex, I got my ovulation tests July 1st so I started using them I’m currently 5 days late, negative pregnancy tests and today my ovulation test came back positive, but I’m also having cramps like I’m about to start my period but could also be ovulation pain? So I’m confused on how I’m already ovulating but almost about to start my period ? 😒 any advice this is our second child and I never experienced this when ttc our first
