Vagina 9-1-1

I've been tested a little over 3 months ago, and have had the same two partners since.. Neither are consistent & I use protection with one (Partner B) with the exception of like 1 time because me and my other parter (Partner A) weren't active & it was a slip-up..

Fast forward to present day - I had my regularly scheduled period 2-3weeks ago, a week later me and Partner A decided to give it ago. While having sex I felt pressure but he's bigger than P-B so I thought nothing of it.. Yeah, started bleeding for a whole week so I assumed my period changed.. We tried again today & same thing only no week long bleeding. Only a little.. I'm scared & don't know what's wrong 😕?

Should I get tested again?
