Bleeding after sex while pregnant

So me and my hubby had sex and I was on top because that’s the most comfortable position I’m 8 weeks along .So he came in me and I just stayed on top cause I was tired so I proceeded to go turn on the light and clean the sperm so I could go shower when I noticed a red spot on hubby and told him was was that n it was blood and I thought it was from him at first but no it was form me and I went to go pee and wipe and didn’t see blood only when I stick my finger it comes out w blood ?!Is it normal ! Should

I go to the ER I’m scared (first pregnancy)
