well. after being 3 days late I had started my period. I've never been late except for when I was pregnant. I spotted with my first two pregnancies. I started my period had a full 5 days and now it's dark brown spotting.. I've also never had that. has anyone had this happen to them? my breast are sore and I feel tight in my pelvic area. I'm still moody as hell and want to cry over everything. I cried because my husband said the simplest thing earlier. help?
