Hi,
Welcome to ehealthforum,
The spotting that you describe could be due to the withdrawal bleeding after removal of the IUD. If your ovulation has returned immediately after stopping with birth control use and if you have had ovulation, chances of pregnancy are possible. Wait and watch for your periods. Look out for development of any other new symptoms suggestive of early pregnancy if you suspect chances of pregnancy. If you do not get periods within 10 days of expected period dates, or if you get abnormal periods, or if you develop any new symptoms, or if you suspect chances of pregnancy, you should consider visiting your doctor/gynecologist for thorough examination (to confirm pregnancy related changes/signs in body) and blood/serum HCG level test (to confirm/rule out pregnancy accurately). If pregnancy gets ruled out, further evaluation would be needed to look for the underlying cause for your spotting and appropriate treatment would be started (based on examination findings and investigation results) to help you in controlling the spotting and also help with getting pregnant. Have diet with foods rich in zinc content to ensure better maturation of egg and sperms. Monitor cervical mucus changes and the BBT (basal body temperature) charting to predict your ovulation and time your intercourse for having fruitful results. Have intercourse in positions that allow for deeper penetration for high deposit of semen. Be in regular monitoring and follow-up with your treating doctor/gynecologist and report any new/abnormal symptoms immediately. Drink plenty of water. Take adequate rest. Maintain healthy diet and lifestyle.
Take care.
