Ovulation Pain

I've been experiencing pain during intercourse for years now (in certain positions with deep penetration) since I had my Mirena IUD in and it continued after I had it removed. Drs have told me it's about 6 different things and unfortunately I've just learned to avoid the painful positions. I just started tracking my ovulation with Glow, and I noticed this month during my 'fertile window' extreme discomfort and pain throughout the day and night. It went on for 48 hours then last night during sex it was difficult to avoid a painful position. After sex I started cramping really badly and it was even shooting down my legs. Does anyone else experience pain with ovulation? I read it's common for 20% of women. Just wondering..
