TMI Post (About my Butt)

Madison
So I've struggled with constipation on and off since childhood. This morning I finally had a BM after a few days and had some bleeding with it. More than streaking on the toilet paper but not soaking through it or anything. 
About an hour ago I went pee, and wiped my behind just to make sure I wasn't still bleeding, and the toilet paper came away with some very dark, bloody stringy mucus?!?! I've never seen this before. 
Pretty sure I had an anal fissure last week, but it went away with some baking soda baths. 
I don't have any pain in my rectum, but am having some pain in my lower-radiating-to-mid left side. 
Baby girl is moving fine. 
Should I be concerned? I'm scheduled for my 22 week appointment on Thursday. Should I be seen sooner?
