Cramping AFTER full cycle

So around the 17th of last month, I had what I think was my period. I bled ALOT the first day, then on & off for about 3 more days. Afterwards, I was still cramping a bit, which was the week of my ovulation. I'm 2 days into my "normal week" before I start my period again, & my lower abdomen is still cramping. It's not all the time, & it doesn't hurt, but I definitely feel it. It's like a sharp pain in my uterus up to my sides sometimes. I was just wondering if this happens to anyone else, or if I'm the only one? If anyone has any tips as to why this is happening, please let me know. Thank you!
