I'm 24 and have 2 children. I have always had problems with my menstraul cycle or lack of it. I haven't had a period in over 9 months took several tests all negative. The last 2 weeks I have been experiencing cramps and excessive yellow discharge. (no odor or itch) I have had a pelvic ultrasound and bloodtests run everything came back normal, but I don't understand what's happening. Any insite on my issue would be greatly appreciated.
