I stopped having periods may this year. Been to the doctor a few times and so far nothing is abnormal. It's not a thyroid problem, not stressed, no weight problems, no stds. From October 27th-31st I had a strange thick snotty discharge that only came out on tp. Then nothing until December 25 I started having it again only this time with cramps. Could it be cancer? Or is this my period? I've also had constipation off and in since October, lots of heart burn, gas, fatigue, mood swings, threw up a few times. Negative pregnancy tests. The outside of my vagina is severely itchy too. Not a yeast infection.
