Actually yesterday me and my gf where having sex for the first time...but I took out my pennis on time before my sperms splashed...but I doubt that my sperm may have got into her ..so I gave her unwanted 72 yesterday in 12hrs.....yesterday she was bleeding for like 5hrs after sex ...then after taking tablets the bleeding stopped today. Question 1. Was she bleeding because of periods or sex....if because of periods then what to do now because her bleeding stopped. Question 2. Is there any prob i gave her the tablets in this unsure situation Question 3.what should I do next? Question 4.will she be okay? Question 3. Someone Plz give me because there is no one who I can share with in this situation and both of us are really scared..
