Possible Implantation Cramps?

Gwyn

Started having cramps on Friday, the 14th and am still having cramps as well as some lower back pain. My periods range from 32-37 days but I know that I for sure ovulated. My progesterone levels on day 21 were 10.7 (this made my first time ever ovulating). I had a D&C done in December and my doctor said sometimes it makes things easier to stick after a D&C so I’m hoping that’s the case! Could these cramps be possible implantation cramps? I never have cramps before my period so I’m just not sure what to think, especially from where I’ve never experienced ovulation before. I definitely feel different too, but all pregnancy tests I’ve took come back negative (which it may be too early for me to be testing). Please help!!
