Conatant Cramping

Hi guys, please help. I've had constant, period like cramping for a month and a half now, since getting off the pill. AF did visit a couple of weeks ago, but like I said, it's just been cramping every single day. Literally. They are sometimes quite bad and I expect AF, or ovulation (I think I did ovulate, no tests done but had other symptoms such as well, cramping, clear CM, acne, etc). Has this happened to anyone else?
