I've been so hopeful but after 4 BFNs I'm convinced I'm not pregnant . I am currently 6 days late. Aug 27 I got a positive OPK, had ovulation pains an everything. I have a perfect 30 day cycle and myexpected start day was sept 13, still no sign of AF. Anyone else with me? My next expected fertile period is sept 24-29, but since my cycle is all out of whack, has anyone experienced skipping a month?
