hello everyone my last monthly period was feb 28th my cycle ranges from 30-33days. i was expected to ovulate january 12. i am 18 going 19 i had sex for the very first time on sunday 7th of February at around 9pm unfortunately and regretfully it was unprotected. He pulled out and ejaculated outside of me but i was worried at pre ejaculation even though he urinated before. the next day i took plan B at around 2pm and took the next pill at 6pm (i was to wait 12 hours between but i didnt) so scared that i took it wrong i went bk to the rx on wednesday and got another pack and took the first pill at 12 noon. my boyfriend tried having unprotected sex with me again but this was for like abt 20seconds. i took the 2nd pill at 12 midnight. the following week thursday i got some brown bleeding which the next day got pink then red then heavier. this lasted till today. 5-6 days which is the normal time for ma period. i took a pregnancy test yesterday clear blue and it was negative i know it is early to test but i did i will test again next week wednesday. i was expected to get ma period this saturday normally. my questions are is this ma period that came early or withdrawl bleeding? did plan b work? what are the changes of pregnancy? and if this is withdrawl bleeding and i expected to get ma period this week again? where am i gettn that much blood from?
