Okay, so. AF was one week early, lasted 4 out of the normal 6 days. Was not as heavy as usual. I've had nausea after eating and sometimes just randomly and the TMI of, a lot of gas.. I'm not sure if I should count this as a memstrual or still take a pregnancy test later. Has anyone else experience something like this? Is this normal or should I be worried (for lack of a better term)?
