Hello Doctor, I need advice regarding a possible pregnancy risk and emergency contraception. Details: My girlfriend is 19 years old. We had intercourse on 19 October at around 4:00 PM. Her next period is expected around 29 October. We were using a condom during intercourse. I was about to ejaculate and decided to do so while still inside her, assuming the condom was properly in place. After withdrawing my penis about a minute later, I noticed that the condom had slipped off and was still inside her vagina. My penis was outside the condom, and I removed the condom manually. My concerns: Case 1: The condom stayed on throughout intercourse and ejaculation, slipping off only when I withdrew. If the semen remained inside the condom without leaking, is there any significant pregnancy risk? Case 2: What if the condom slipped off during intercourse without us noticing, and I continued penetration without it and ejaculated inside her vagina? Could this cause pregnancy? What should I do
