I have had reproductive problems since I was 12. At 16 I was diagnosed with endometriosis and possibly the inability to conceive. At 18 I was diagnosed with stage 4 endo, PCOS and my tubes are closed due to scar tissue build up and I cannot conceive confirmed. I am now 20 and my periods have gone from every other week as a teen to once a month usually within one or two days of the last month. This week is different. I have had horrible cramping as if I am on my period, a one week late period, and white vaginally discharge for 2 weeks. What could possibly be going on?
