I just felt like a cramping on the lower part of my belly, I think Braxton Hicks, it was so strong! It's coming again!

Maybe TMI but yesterday after having sex I had a discharge with some blood.

Now I'm trying to sit, but everytime I get in a comfortable position I pee a little.

Can somebody tell me if this is normal?

should I go to the hospital? I'm freaking out here!

Update: I had 12 contractions in the last hour, so I'm going to the hospital
