Confused:prelabor??

Jade

I am 31+6 and this week has been a rough one. I have had the following:

-Exhaustion

-Frequent poops/loose poops

-Constant backache varying in intensity but uncomfortable enough to keep me home since thursday.

-Diarrhea like cramping(sometimes its gas, so its hard to tell)

-Lower abdominal/Vaginal pressure especially when standing or sitting

-Swollen vaginal area

-Possible hemmoriod...could be swelling from all my lady bits?

Is this normal 3rd trimester stuff or should i consider this prelabor and call/go to dr?? Baby is super active btw.
