What are the chances of being pregnant? he put a condom...

Hi,
Welcome to ehealthforum,
Since the pullout/withdrawal method of contraception is associated with highest failures (pre-cum/pre-ejaculatory fluid is known to contain sperms and no man can be 100% sure that pre-cum/pre-ejaculatory fluid did not leak out during vaginal penetration without use of condom), chances of pregnancy cannot be ruled out completely (especially if you were during fertile days/around ovulation time at time of intercourse). If you had been regular with taking your birth control pills at scheduled time daily without missing pills in between, (and if this is not your first pill pack use, or if this was your first pill use and you have not been sexually active without protection during first 2-3 weeks of getting started on the pill pack), you should have the protection. Wait and watch for your periods/withdrawal bleeding. You can consider getting started on the next scheduled pill pack as usual if chances of pregnancy are ruled out. If you notice abnormal bleeding or appearance of new symptoms, you should consider visiting your doctor/gynecologist for further evaluation to look for the underlying cause. Treatment as appropriate (based on examination findings and investigations results) would be started to help you regulate your periods. Use back-up protection for additional protection if you are worried about pregnancy, and avoid having unprotected sexual contact if you are not ready for pregnancy. Be in regular monitoring and follow-up with your treating doctor/gynecologist and report any new/abnormal symptoms immediately. Take adequate rest. Drink plenty of water. Maintain healthy diet and lifestyle.
Take care.
