cramping since ovulation???

Hi ladies, I have had cramping ever since I've ovulated this month, I was at the hospital for a internal scan ( to check lining and follicles) which were all ok,  as we're are starting iui in the next few months, my doctor said I ovulated the day or two before in which we did do the deed,  I'm now about 9dpo and the last 2days I'm cramping more to the left, been so snappy and emotional to my husband, and feeling light headed and sick :(

My cycle are round 24-25 days so af should be here sat, which I pray it doesn't come, had anyone got any suggestions what my cramping might be? Xx
