So me and my girlfriend had sex and we didn't know she was ovulating. I used a condom and after that i filled the condom with water and there was a very very small hole near the base of the condom and not the tip of the condom. We were worried about precum and she took the morning pill. After 1 or 2 weeks we expected her period and at first there were red spottings and then brown but then eventually she bleed for about 3 or 4 days with normal red blood ( she filled the tampons with blood). My question is. Was that her period? Should i be concerned? She said she had her period and it was normal, but it should be ok?
