Im currently a day late on my period, with endometriosis... but I've been experiencing medical issues for the past two weeks. They thought at first it was pelvic inflammatory disease but I tested negative... they have me on two kinds of antibiotics cause my blood work did show infection. Been having alot of pelvic discomfort, lower back pain, sore breast and nausea, with mild dizzy spells. They did a pee pregnancy test at the doctors, but I was still a week out from my period then. Should I even bother taking a test. I went off another app at the beginning of the month, that had a ovulation days different.
