Bleeding TMI

Okay ladies.. so im 23 weeks pregnant .. and my husband and I were doing a little foreplay before sex .. and he was fingering me for quite some time.. I came twice and was about to for the third time when he pulled out amd hes fingers were all bloody .. I went straight to pee and wash.. and there was very light blood .. should I be worried? .. should I wait it out .. or go to the Dr. Any suggestions .. experiences if this happened to you.. please.. thanks in advance.
