I've been having unprotected sex for the past 2 weeks now. I used the Plan B 3 times within 1.5 weeks. When i went to see my Doctor 2 days after having unprotected sex in order to get a patch prescription, she advised me not to take another Plan B to cover the unprotected sex I had 2 days ago. Mind you that I started bleeding, like it was my period, just lighter than my usual and it was 2 weeks earlier than my expected period. Could that actually be my period already? Also, She said that the Plan B is a double dose and taking it 3 times in 1 week is a lot and should still be in my system to protect my last intercourse 2 days ago. Is this true? I followed her advise and didnt take a plan B. And then I started my patch 2 days after. Could there be a chance I'm pregnant? I also had unprotected sex before waiting 1 week of having the first patch on and used Ella emergency contraceptive to cover it. Is this dangerous? Please give me more information on this thank you!
