Fucked a girl unprotected (ik) on the 5th. Shes telling me today thats shes been late for 2 days. I pulled out but she thinks obviously I did it too late.

I tell her it’s fine prolly, it’s okay to be a couple days late but she told me shes never been late before. Then fucking tells me she was on antibiotics so it could have messed with everything (🤦🏽‍♂️)

I recommended plan b but she says its only effective for first 4 days and today is the 11th so it’s been 6 days.

What should I do? Any suggestions?
