Confused much 🤦🏿‍♀️

So I had some bday unprotected sex on the 16th took plan b on 18 then had unprotected sex again on the 18. The thing is I threw up like 5 mins after taking the pills. Every time I took the pill I bleed few days after or the next day. It is now 7 days and I have no symptoms except mild cramps that come n go no spotting and clear discharge and I’m super horny 🤦🏿‍♀️. Any advice is welcome
