Has anyone ever had this happen?

Anyone ever been 15-16 days late for period and then it finally showed up, but it was lighter and shorter than normal...And then went on to get a BFP? I guess I’m going to test again. In the mornings if I don’t eat something pretty quick, I get really nauseated. My stomach feels super bloated and I’m extremely constipated.

Please let me know if anyone else has had a similar situation.
