Call me crazy

Ok so I am dying to know if anyone else has experienced this.. My husband and I have had sex three nights in a row TTC during my ovulation days. I swear my body feels different but don't want to just be psyching myself out. Has anyone else ever felt bubbles in their abdomen? I describe it as sprite bubbles in there.. Also cramping a few days after.. But not pms cramps and period isn't due for about two weeks.
