TMI bleeding and such

I’m 28 weeks. Last few days I’ve had painful runny poops, I wouldn’t say diarrhea because it stops but everytime I poop it’s bad. And I’ve had spotting when I pee. Cramping in my lower abdomen. Some discharge. I’m worried about the placenta from what I’ve read. But again I think some of this can be normal. First time mom so sorry if this is a lot.
