Unexpected bleeding. Period or am i broken?

My husband and I had sex a couple days ago for the first time in over a month. When I went pee after, I found I was bleeding just a little. I thought maybe we were too intense after a long time of inactivity and left it at that

Next day, still a bit of bleeding

It's been 4 days and still small amounts of bleeding and I'm not sure anymore if it was just from the sex after a long time of nothing.

My cycles are extremely irregular so I thought...maybe this is another period.

(I stopped birth control last year, had no period for a year. Finally got the worst and most intense period on Feb 9). I think it's unlikely its another period so soon.

Anyone have thoughts or reassurance ?
