Hello,I am Lincy,I took 100mg medroxyprogesterone(provera) to help control my withdrawal bleeding 9heavy)after I stopped my oral contraceptive pill 4 days ago as I started spotting.When I am I allowed to start my oral contraceptive pill again,Please advice.I take the pill not to prevent pregnancy,but to keep my endometril lining thin as I bleed heavily during my periods.Thank you.
