Pelvic pain

Liz • One 21 month old healthy boy, one angel boy lost at 25 weeks. TTC #3, hoping for my rainbow!
TTC #2 after a late loss in February. I've been having bad cramping for the past 3 days- I'm on CD 19 after taking out Nuva ring on May 2nd. No idea if I've ovulated, just scared because of this pain. I don't have endometriosis or ovarian cysts that I know of but worried about both... Anyone else have this kind of dull aching cramps when it's not time for AF? I'm calling the doctor first thing Monday to try and be seen...
