I took plan b.

Okay so on Tuesday I had sex with my boyfriend.. the condom broke so he fully came inside me. This was on the 29th on the last day of my period when barely any brown stuff was coming out. It was around 10:30 and I took plan b around 11:30. Usually girls feel symptoms but it’s been almost a week and I haven’t gotten any. I currently also have a yeast infection. Today I started having pinkish brown orangey discharge. I’m unsure if its the yeast infection or the plan b. I have to wait 4 weeks for my period and I can’t stop stressing and googling about it. Has anyone had the same experience?
