should ovulation hurt

Ella
For the last year I have pretty much been feeling pretty shitty about everything period related. 
I have been having major cramping today (to the point where I feel like I may pass out) checked <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> and I'm ovulating. Should I really be feeling this bad? 
All in all I feel like I'm on a 24/7 period because of the pain and cramps I have been having. Periods have never had a regular pattern and I'm either 3-4 days early or 6-7 days late which makes planing anything ridiculously long. 
I have a hospital appointment to check to see if I have endo, but my doctor so far has only been giving me painkillers which make me a zombie 😭
