Aroused And On Your Period Is It Dangerous To Have Period Like Flows When Aroused And/or Climax And Not Being On Your Period?

Is it dangerous to have period like flows when aroused and/or climax and not being on your period? - aroused and on your period

I am 21 and sexually active, have for several years and have no bleeding during sexual intercourse until recently. At first I thought it was too hard, I bled a little during and after the period in which it flows. Now, if you look, or climax, even without penetration time I experience bleeding and cramping. This was more frequent during the last months. I have the shop fire since October. I am very concerned that something can not be in order.
