Today ive been feeling some sharp pinches in my lower right side then some intense cramping in the lower part right above pelvic and in uterus! Now im just having sharp stabbing pains on and off in my uterus! Could this be the egg finally implanting this is the first time ive felt this and my period isnt due until 9days ! I also tracked Ovulation and i od CD 18 got my positive CD 17!

Could this be implantation pain?
