I had sex with my partner on 5th to 8th. We had sex for 5 times and only 2 times we used condom rest we didn t. There is a possibility that I may have ejaculated the sperms inside her. She had taken 3 i-pill (contraceptive pill) after our sessions. After 2 days she complained about swollen legs and pain. This was our first time and we had sex soon after her periods got over. A week later she saw little blood coming out of her vagina. Is she pregnant?
