I need help

Bunny

Little background. I have had regular af for about the last two years. husband and I went on an anniversary getaway on July 2nd thru 4th with unprotected sex. according to glow I should have started af on about the 15th. Also according to glow I would have ovulated on or around the time of the getaway. glow says I am about 10 days late for af and I have had several bfn. now having occasional pains around right ovary. I am not sure what is going on. Could it be pregnancy or possible menopause. I am only 41??
