Help! I'm scared!

Jasmine
🤔 I have been wrecking my brain trying to figure out what's going on with my body. After intercourse I noticed blood. A pinkish red color. Not a whole lot but more than when I first come on my cycle. So I wiped, got in the shower then put on a pad. The next day (Friday) I feel like I'm on my cycle the bloating, light cramps and everything, but still no blood. I'm thinking maybe I'm just really light this month, I continues my day as normal. I go to work, half way through my day I go to the bathroom to check to see if I'm bleeding yet. Still there is no blood. Ok cool maybe I'm extremely light this month since technically I came on pretty early. Moral of this story it's now Saturday and still no signs of blood! This has never happened to me before and I'm freaking out. Someone please tell me if I need to see a doctor or not? Could it just be intercourse?Â
