I've had pretty regular periods for my whole life. Any fluctuations stayed within a few days. Occasionally, maybe once per year or two, I'll have 6 weeks w/out period, then it adjusts accordingly (I guess kinda like leap year).
For the first time ever, I've gone without a period for 3 months, going on 4. I took a pg test last month, with morning pee, and it came up negative (fyi - it was given to me by a friend that ordered a bunch of clinical tests at once that have an expiration date about a year from now). Some of the symptoms I've had lately that were out of the ordinary include, stiff joints (a couple months ago) and very tender breasts (currently for the past month).
I have no discomfort in the area near the ovaries/uterus. I also don't seem to be getting bigger, although I am generally overweight (~30 lbs) so it's possible if I am pg I'm not showing yet. I should also mention that I am 42 with one 6 year old child, no miscarriages, no medications.
Any thoughts why I may not have my period? Could I be pregnant? If not, is missing my period something to worry about much? What should I prepare myself for when going to the doctor in terms of tests/procedures that I should avoid?
Any advice is much appreciated!
