It is common for young women to have irregular periods when they first begin to menstruate. This means that ovulation (when a womanâs body makes eggs) may not happen for a few months or even for a few years. So you may not have menstrual cramps when you first begin your period. After one, two, or three years, when your hormonal system is more mature, you might have more severe menstrual cramps.
The lining can attach to the ovaries, fallopian tubes, intestines or other structures in the pelvis. Adenomyosis occurs when tissue from the lining of the uterus grows in the muscle of the uterus. Endometriosis may cause pelvic pain, especially during menstruation. Hormones of the menstrual cycle cause the endometriosis to bleed each month. This can be painful and result in the formation of pelvic adhesions, also known as scar tissue. Blood trapped in the ovary can build up into a cyst.
