Opinions/thoughts?

Okay ya’ll, I need some input. I had sex for the first time the other night and while it was quite amazing in all the best ways, I can’t seem to stop bleeding? I know its normal to spot/bleed for the following two to three days, but I’m on day 4, and I barely spot all day and then bam! Bright red blood. Annnd repeat. I’m going to my doctor Thursday morning but I wanted to know if any of you ladies experienced something similar and if its something I should worry about?
