Hello, for the last several months I have been pretty regular with my cycle, typically starting my period on the 7th of each new month. My period came as normal last month (Oct 7), then when it hadn't come by the 9th of this month (Nov), I started to wonder if I could be pregnant. I was absolutely CRAVING nothing but apple juice, but have had no appetite otherwise. My mood swings are worse than I've ever experienced. I also threw up one morning out of the blue. My period continued to be delayed for another 8 days after the 9th, and this today being day 10 of being late I finally started bleeding. I am having bad cramping that Tylenol will not help at all; and the blood went from light and watery orange, to brownish mixed with a little red, to actual period-like soaked tampon overnight. I have seriously bad back pain too. Is it probable I may actually be pregnant ? (Update: I took a HPT and got a negative result two days before the "period".) This only started 24 hours ago. What should I do and could I be pregnant ?
