What is going on???

Hey mamas, i’m 6 months postpartum and experiencing what I assume is my first time ovulating since birth. Today is day 4 of lots of twinges in my lower abdomen and LOTS of stretchy CM. Painful sex last night when he reached what I think was my right ovary. I just feel off. I’ve had several negative pregnancy tests. Has anyone had ovulation symptoms that lasted for four or more days? I’m wondering  what the heck is going on with my body! This is my third baby and I’ve never felt like this on my first cycle back.
