Looking to see if anyone else has experience with this. I stopped using my Nuva Ring and had a usual withdrawal bleed. The following months I missed periods and had negative pregnancy tests. My OB gave me progesterone to stimulate and it worked but now I am late again and still bfn. I have read on-line 6 months is the magic number for becoming regular. Just looking to see how long it took others to be regular after bc or any other problems. Thanks in advance!
