My period has been on time for the past few months on a 28 day cycle, but last period came a week late. It was different than usual but it wasn't extremely light. I had very bad cramps the first day of the period and my period lasted 6 days. The week after I woke up with diarrhea for a few days and to this day my bowel movements have not been the same. This week I feel like I'm having more vaginal discharge than usual. I took two preg. tests within a week of each other and both were negative. I am sexually active with my bf but we have used a condom every single time.

Any advice before I go see the dr? Thank you...
