Blood when i wipe!? And pee is tinted red?

Samantha

Yesterday i was cramping in my lower stomach and then i went to pee and when i wiped there was like a drop of blood. Ok, so then today im not cramping at all, i went and then i wiped and this time their was a little bit more with a tiny tiny little blood clot on it. Should i be worried? im 23 weeks pregnant also...
