Ovulation or implantation cramps??

Skylar
I'm confused and need some wisdom! Ttc baby #1 and I'm not sure when I ovulated (it was anywhere from 18th-20th) because I had ewcm and twinges/light cramps in my lower belly during those days. We BD for 3 days straight (17th-19th) and now I'm having painful cramps in my right side. I'm almost positive I ovulated on the 19th or 20th but I could have sooner because my ewcm has been a lot less recently. So is what I'm feeling ovulation pains or implantation pains?? They feel like a pinching/stabbing pain in my right side. Thanks!
