I recently switch my birth control from Sprintec 28 day tables to Norethindrone Acetate and ethinyl Estradiol Tablets USP 21 days. Since I switch to the Norethindrone one I haven’t started my period yet and it had been two months now. Should I be worried?
Do a pregnancy test to be sure, but if it's negative, it will just be the change of birth control causing the delay. That can happen with artificial hormones, so just keep taking your pills as normal & things will eventually fall into place again.
