I seem to have a multitude of problems.

Im not sure where to begin, I seem to have a multitude of problems. A few years ago I started to get irregular periods, up till this point I was able to run my calendar by them. The first time it happened it was after sex with my ex. I didnt have a period for 2 months. I thought I was pregnant, took a pregnancy test but came out negative and a few weeks later I got my period. After that, the period lasted almost a full month, but with days with just spotting. Now they come and go, some will last a month or up to 5 months with spotting mostly, other times I will go 2 months without. On top of all that, I have had a clear vaginal discharge for a while. Ive also experienced abdominal pain, pain around the sides, pain beneath my right rib cage and occasionally pain in the middle of my chest. I get lower back pains alot. On a few occasions, the pain in my back would be so severe it hurt to breathe while standing, this also occuried when I got the pain beneath the right rib cage.
