You may want to consult with a GI doc. This sounds exactly like a condition I've been dealing with for over thirteen years that isn't related to pregnancy called ulcerative colitis. It is very similar to Crohn's disease. Both are manageable with proper diagnosis and medication. I know I wasted many trips in the er when I was initially sick because there is really nothing they can do there. Hope this helps.
If ur seeing blood clots and mucus... u may wanna go to the er.. if the doc isnt concerned that might be her call but it does sound scary. Since ur so close to delivering u shouldnt risk any infection.
I have been batteling constipation, hemhorroids, anal fissures and bleeding this whole pregnancy and I told my doc.. she didnt seem concerned either.. and told me to live it out.. I didnt trust her so I went to the er when the bleeding got really bad.. told me bed rest, diet changes aka more fiber and water, stool softeners etc... they also showed me techniques on how I could deal with hemhorroids. So it was a trip worth taking.. I suggest u go..
Just for the peace of mind
I had really bad hemmeroids and fizzers (its what the doc called them) when I was pregnant with my son and every time I had a bowl movement I would bleed. Bright red blood with no clots. I had issues with this well after birth but I did not have anything like what you are describing. I would definitely get a second opinion. Take care I hope everything is ok. Thinking of you!!
Sounds pretty scary! I would just go to the er and get a second opinion!!!
