My husband and I have been trying to conceive for three months. Last night, I began to have cramping like my period. No spotting or blood, but occasional cramping that has been on and off. I don’t usually cramp until the day before my period so thought this was strange. My nipples are also extremely sensitive. I am about 9 days past ovulation according to my ovulation test and a week out from my period. Could this cramping be implantation or is it AF? What are our chances?
