I stopped taking cerazette just over 3 weeks ago to TTC #3. No withdrawal bleeding at all. Had 2 BFPs on 22nd and 23rd Oct followed by about 800 BFNs Must be a chemical. I had one before I conceived my daughter except I started bleeding 2 days later. But this time... nothing. It’s been 10 days now and still no period. Just light cramping every evening. Has anyone had anything similar? When did your bleeding start?
