Been trying TTC for a while now, have been to the doctors for checks and came back normal. My periods are erratic and not normal in the slightest, at the moment I am 80ish days overdue and took a couple of tests, all coming up negative. This happened this time last year as well, was 120 days before getting my period. Hard to map out fertile days. Has anyone else had this problem, starting to lose faith and give up.
