35 days late

I’m 35 days late and docs said I have to wait untill I’m 3 months late... I’ve been ovulating and checking so that’s normal.. my stomach is in agony and feel like my periods are coming but are not .. this has never happened to me before.. my husband got checked 2 months ago and he has low sperm and morphology but docs think the test is inconclusive so we have to get tested in 1 months... I have our first fertility appointment next month..my periods ARE NEVER LATE maybe by 1 day max... has anyone ever gone through this?? I keep getting random cramps and my boobs are huge and hurt so much help!!! Been getting BFN also
