Bleeding weekish before period when orgasming? Scared.

32F No meds, no birth control Not pregnant No issues to note other than..

I am freaking the hell out. Complete panic. The last two times I orgasmed, I spotted. I am on day 27 and also bled on day 22. I recal 'not' having this predicament anytime before day 20's. It's light red spotting and periodesque cramps. I am so scared I have cancer or something. I also had light blood last time I physically and aggressively masturbated with fingers which was day 19 last month, but that was a small tij of blood. The last time I had my period it lasted a whopping 1.5 days and then was gone.

I am going to go in but am extremely freaked. Can anyone relate or tell me anything so I am not flipping out???
