TMI Should I be worried! TMI

I’m staying anonymous. But for the last few days I had poop that was just too big to push out. It hurt when I tried. So I’ve been super constipated. Today I tried my best to get it out. I did, and there was blood in the toilet. Not from my vagina, but from my anus. It was bright red when I wiped, like a period. I almost passed out trying to push that demon out from me. Should I be worried about anymore bleeding? If it doesn’t stop should I go to the ER? I’m almost 16 weeks, but the bleeding was NOT from my vagina. I just don’t want to internally bleed.
