Hello, I am 32 years old with Hypothyroidism, last week my TSH levels were checked and are in normal range. I have been lightly spotting since ovulation and was sexually active with my husband. I am concerned right now, because I am 6 days early and have thick, dark, almost black bleeding when I wipe (approx. 30ml). I am also have cramps like I would on my period. My concern is uterine fibroids/polyps or early menopause. What is your thoughts on this???
