my boyfriend wasn't in me for more then 45 seconds but I took the pill 4 days later & it seemed to have worked, I took it out of paranoia and got my period 3 days later. it lasted 6 days (my cycle last like 5-6 normally so I wasn't weirded out) also went on Previfem and have been on it for almost a week. I had sex today, the 11th of October since my period ended yesterday and it hurt a lot at first, I was also really tight which isn't that normal and my boyfriend wasn't going hard at first yet i got pain and then stopped getting it when we switched positions. any help?
