I Am 38 Years Old And Have Been Diagnosed With

I am 38 years old and have been diagnosed with endometriosis. I had surgery to remove scar tissue a year ago. My husband and I are trying to have a baby and I started my cycle, on time, but with really heavy bleeding. I used 14 super plus tampons in a day and half and am now tired and have been experiencing squiggly lines around my peripheral field of vision. I do have heavy cycles, but the vision issue concerned me. Any suggestions??
