Bleeding after sex 🤔

I am 9 weeks and 5 days today. Well since the beginning of finding out I’m pregnant I always bleed after sex... I went to the er around 6 weeks and they saw a heart beat.

But it happened again, but the bleeding is heavier and bright red... but will stop within 5 minutes. I just want to see if anyone else has experience something similar.. I’m also new at this whole pregnancy thing.
