Don’t want to get my hopes up..

Currently CD34, period is two days late (possibly) however I have had as long as a 40 day cycle before. Pretty sure I caught the start of a positive ovulation test on the 7th December & we did BD that evening, which would mean that period IS two days late. I just don’t want to get my hopes up & I’m now doubting that it was a positive test & I’m worried that if it wasn’t positive we would have missed ovulation because we then went a few days without sex. 😬😬 I have no pregnancy tests & trying to hold out because it’s usually turned up late! Trying to keep positive!
