Alright thank you. I'll start looking out now.
You have a lot of pelvic pain because the baby has substantial weight that far in and is putting pressure on your pelvis. Baby also could have dropped, which causes additional pressure.
Your mucus plug can come out and regenerate multiple times during pregnancy. Some women don't have that happen until labor, some women don't even notice it on their toilet paper. I'd start looking out for it any time now.
