Hi. I am years old and in January I has a vaginal and abdominal ultrasound because of bleeding between periods. It was to rule out fibroids and I was told that based on other symptoms, I was in perimenopause. I will get a regular menstrual period and about a week to 2 weeks later begin to bleed again. It can last up to 2 weeks at times despite my being on birth control pills. The problem is the cramps have become unbearable. They are in my thighs, my legs, my entire back...it is horrific. My stomach bloats. I have taken Ibuprofen and Tylenol and both work for only a short time. I feel like I am in labor! Why is this happening?
