Normal? TMI

Stacey • One boy, one girl, Two in Heaven and another on the way. Endo Warrior, Bicornuate Uterus

I am 3 months pp after emergency c section and bleed lightly for approx 8 weeks, stopped for a few days and bleed for another 2-3. My fiance and I started having sex almost 2 weeks ago, protected. The past few days my uterus and incision area seem to be tender and today I got this very thick mucus, almost like gum on my underwear, and stringy mucus when I wipe. Just wondering if all this seems normal? First time going through post pregnancy so I have not a clue.
