Hey Babymuddle,
I got very similar cramping this cycle, as it was my first "o" cycle. It started the first day of O and then continued until AF. I am presuming it is because it is everything getting used to being off the pill. If this is unusual for you then it could be a good sign! You wont know for sure until AF is late or BFP, so don't stress too much. Stress only causes hypersensitivity and then before you know it you will imagine you are getting contractions, and it could be just gas!

Good luck for next week,
