I'm Afraid I Have Endometriosis. I Have A Strange Pain/pressure

I'm afraid I have endometriosis. I have a strange pain/pressure type of feeling in my lower abdomen. I feel naseous a lot. I have irregular periods. During my periods, I have a lot of cramping but mostly just period pains. When I'm off my period, I have these other pains. I had an ovarian cyst burst about 2 months ago and a yeast infection about 2 weeks ago. What do you think?
