What about sex ?

So I need help! My sex drive has been gone for the longest. It’s finally back and Sunday my s/o and I were doing the “task” and we had to stop because of bleeding. Went to the E.R and everything was ok. I called my dr the next day and all she had to say was “it’s normal , you’re dehydrated “ which just boils my blood because I drink over 8 cups of water a day! Should I just get over being mad that my dr didn’t seem to concerned or even want me to come in to check on me? I’m just so scared and cautious about everything..
