Katie 🇬🇧 • TTC 👼🏼👼🏼👼🏼 Low AMH

Recently had MC so didn’t know when AF due or when ovulation was so was using Clear blue digital.. had 3 days of flashing smiley faces, was waiting for static smiley but AF came 🤯 Still getting flashing smiley (high fertility) whilst on AF. Surely this can’t be right??
