i took a plan b twice in 5 days

so me and my boyfriend were having amazing sex thursday and he came in me this is the first time i ever even let someone do that even tho i didn’t really let him it kinda just happened i took a plan b the same night friday we had sex again but i’m pretty sure it was past midnight he came in me again like a dumb ass lmao🤦🏽‍♀️ we don’t usually have unprotected sex it was just in the moment we wanted to we have sex everyday so we didn’t think once without would hurt but we were both drunk i didn’t think i needed to take another plan b because he said it would be fine it hasn’t been more than 72 hours but i didn’t think he was right so monday i took another plan b because i called and asked and they said it only works for one time of sex and now every time ive went to use the bathroom a little bit a blood is on the toilet paper is the plan b messing up my hormones i know it isn’t good to take it twice but the woman on the phone said to and i wanted to be safe
