TMI!!!! Help please

Bambi💜💗🍼 • With the man of my dreams and ready for baby number 5! Which happens to finally be our girl! We are truly excited!
Ok so dr has me taking milk a mag, stool softeners, and pretty much all else to give me the poops... my issue is I am 34wks and 4 days and the pressure I have below and the pain in lower back makes it feel like I really really really need to poop! It doesn't feel normal. I feel like a pipe has been backed up. I am also sure I have hemmroids. So it's very sore. My question to all the ladies is how do you handle or what comfort can you get? This is my 5th full pregnancy, but only girl and man its been complicated. Please help!!!!
