Make sure he trims his nails and files them short before he fingers you again. Ideally, use gloves (+ lube), because that will protect you from any grit he has under his nails, and make him less likely to scratch you, which is what I think has been going on here. You won't necessarily feel the scratch right when it happens, and only notice bleeding and maybe burning later. If he doesn't wear gloves, make him wash his hands right beforehand and use a nail brush to get any dirt out from underneath.
If you don't stop bleeding soon (next day or so), the bleeding gets worse, are getting funny colored/smelling discharge, or a fever, it's time to see the doctor.
You can get infections if his hands are not clean plus if his nails are ling and dirty, he could easily scratch your vagina and harm it. You cannot get pregnant by only being fingered so by taking the morning after pill you alter your hormone levels and maybe that is whats going on aside from the vaginosis. Indeed, go to the gyn ASAP to be sure it is not something serious and get yourself checked. Goodluck!
Hi Mikayla, Your best action would be to go back to your OBGYN, ASP you need more treatment soon as you can.
Good Luck
