Hi dear, I have gone through your question and understand your concerns. Excessive bleeding in the periods subsequent to medical abortion can be because of post abortal dysfunction in the uterine lining, which leads to excessive bleeding. This is controlled by giving hormonal medications, and one should generally avoid getting pregnant while on these medications. You can plan pregnancy once you are off these medications. Hope you found the answer helpful. Regards Dr Deepti Verma OBGYN specialist
