I'm one to be a few days late. Maybe 2 weeks. I have skipped a period before as well. This month is different. A lot of back pain cramping and mood swings. Yet no period. The back pain and cramping is actually new because I always had those symptoms during my period. Lately I've been thinking that I'm pregnant. But all test come back negative. I have a restful appt on the first and I'm refusing to take another test because I know it's going to be negative yet I have hope to get a positive reading. Any advice??
