I'm 16 years old... And my boyfriend and I are sexually active, and he cumed in me... so we got a pill called the morning after pill and what it does is that it keep the egg from being fertilized and so I got my period 2 weeks early and everything was going fine... so I thought :confused:... So I've been on my period for 12 days already and around this time my boyfriend and I have been having sex while I'm still on it but my period is not that strong its kind of like spotting... anyways my point is that Ive never had such a long period before and I don't know what's going on.. I'm thinking it has something to do with the pill... so if you can help me... I really don't know what's wrong with me.. let alone what to do! :(

Here's some info I found when I googled;

Will plan B throw off my period?
plan B has no long-term effect on your monthly cycle. Most women will get their period when expected and their cycle will continue as normal. For some women, their period can come earlier or later than usual and be lighter or heavier.
If your period is delayed more than a week or if you have any other cause for concern, talk to a health professional
