I'm a 27 y/o F, I have always had regular periods, raging consistently between 29-32 day-cycle, lasting between 6-7 days of heavy bleeding, and painful cramps. My partner and I have not using protection for the last 4 years. On Sept my period only lasted 2 days. No cramps, no PMS as usual, it was light then brownish. Now this Oct I was supposed to have my period on the 24, and today I got some spotting. Mild cramping, been pee more frequent. It has not happened to me ever that my period came early, if stressed or sick would always be late. I had a blood test about a week ago, for other reasons where they found my ESR elevated, 37 I think it was the value when the normal is between 0-20. Everything was fine including glucose, THS . I did take a UPT in Sept and came back negative... Could I be pregnant?
