Help..I’m freaking out

So yesterday I post about my random poop that made me bleed. ANYWAYS I stopped bleeding. Well I haven’t felt to hot and Ive had some weird things going on. Like, my entire belly hurts. Like not sick feeling but like pain. Literally from my belly button to the lower part of my boobs, And where my pants sit it HURTS, now I went poop again and I wiped and there was about half an inch of red blood. Not pink but red. The line was small so about this big -> ————— <- I had to show y’all about the size. I do go to my doctor tomorrow at 2:30pm but I’m super nervous and worried. I panic way to easy and idk what to do other than lay down and I can’t stay that way cuz I have an 8 year old and it hurts to lay on my back. So what do I do now..?? Any and all advice is appreciated. Also I am 8+3
