Hi, I am on Day 30 and no sign of AF, did a Boots Early Response test yesterday with FMI and BFN. My cycle has been 27/28 days for the last 5 months and to get to day 30 with no AF is striking me as odd. I had cramping and tingling bbs a few days ago so thought AF was coming, but so far no sign. I OV'd a few days later than normal this month, normally its Day 13 but this month it was 15, so my app expected AF yesterday. My question is, what are my chances of getting a BFP or is AF inevitable? Has anyone had a similar experience>
