I just started Tri Sprintec two weeks ago. Just two days later, I started experiencing severe abdominal cramping which lasted about a week. In addition, I was having to urinate once or twice every hour. Once the cramping subsided, I started feeling nauseated. I've gained five pounds and have the worst cravings for junk food. I'm very displeased. I hope things turn around...is anyone else having similar issues??
