Me and my girlfriend are planning to have sex. Both of us will be 20 when the intercourse is supposed to take place. She has normal menstrual cycle of avg. 31 days. We are planning to have sex on 25th may 2016. Her last period begun on 24th march. We don't have any problem to have sex during periods. We would use on condom definitely, but still there are somethings I want to know. 1. After what minimum time can we take a pregnancy test reliably? Because the Emergency Contraceptive pills will world best only within 3 days. And what can be done in case of positive pregnancy (Knowing the result ASAP). Does the situation become very critical or can it be resolved easily by Doctors, and what would be the cost of treatment in that case? 2. What are the chances of pregnancy during periods? 3. Can You tell me about oral contraceptive pills, their dosage and recommend an OCP.
