Cramping

I got a bruised cervix, I think more than average because the sex and pain during was longer than previous sex. However it's been a day and a half and the pain when I sit in my stomach is gone. I'm still cramping though, I've been wearing a pad just in case. It has very very light amount of some time of colored discharge. I'm thinking it's cause my period is coming? Has anyone had this happen?

I had a bruised cervix before, the sex wasn't as long and it hurt a lot but the pain did go away overnight. That's why I'm thinking period? Help. :(
