I'm trying to stay calm, but I started my period on Feb 28 last month. I had a stillborn in October and my period has been like clock work each month...usually starts the 28th of each month or a day or so before. A lot of times I'll get a moist feeling in my genitals about a day before my period starts or I'll wind up wearing a pad because I feel like I'm about to start. I haven't had that feeling this month and today is the 30th and I haven't started my period. The only symptoms I've had of PMS is extreme irritability, hunger and sore breasts.
