Kirsty

I’m due on tomorrow, and glow days I ovulated about the 8-9th of March, if I did then can anyome tell me when I would test for a positive as they’re all negative tests but my period is a no show and I normally bleed 2-3 weekly atm as I’ve only had the implant out a few months, this is he longest I’ve not bled since having it out!
