Help!!

Two days ago my boyfriend was fingering me and I’m pretty sure he might have scratched the inside, so we stopped. There was a lot of blood so I used a panty liner and then yesterday it look like old blood (brown) mixed with discharge so I’ve still been wearing panty liners. Then tonight I looked and there was a lot of blood and when I wiped it was red. Should I go to the doctor or wait to see if it’s heals in its own? I don’t feel any discomfort besides some ovulation cramps.
