Hello, If the abortion was under surveillance of a specialist and went on uneventfully, there is nothing to worry. Just maintain proper nutrition and have periodic checkup. If hormone imbalance is suspected by your doctor as the cause for the altered bleeding, please get it corrected. Anemia, infections and reduced endometrial surface also can cause such abnormal bleeding patterns. Please establish your ovulation pattern and try to have regular intercourse around your fertile period for quicker results. Hope this helps.
