is this much bleeding 2/3 days after 1st time sex normal?

You should not be bleeding this long - far far from the 10 days when your period is supposed to come. Some amount of bleeding is normal and expected when you have first intercourse and it can last for a few days, but the amount should be more like spotting after a first day or two than something that would need a tampon. Is there any pain or cramping? Is there a chance that this is your period?

My periods are heavy normally would that affect it? Pretty sure its not my period I average a period every 30 ish days its only bin 20 since my last one? Unless it can have brought my period forward. I'm really worried I'm not gonna no if I miss a period or not?! There's enough blood to need a tampon will a tampon make it worse if its my hymen breaking?

Your period definitely could have come early, really, there is no woman who has had every period exactly on time, so - it is possible, especially because of the amount of bleeding. Is the blood bright red? Your hymen was at the entrance of your vagina - on the outside, so no, tampon that is inside your vagina has no effect at all, especially because your hymen is supposed to be completely gone now, after first sex. You can do pregnancy test some two weeks after the sex and if this bleeding continues for few more days you really will need to see a gynecologist. How long does your period last?

The bleeidng started during sex and was only spotting I've never had a period this early before? :-( I'm really scared its not the sort of thing I wanna talk 2 a dr about what am I gonna do ?!
