My cycle is usually 28 day, i guess i fall into the average length. I guess i am one of the lucky ones to have a normal chain cycle.
Hope you get your BFP hun!!! Do you know what CD ovulation was for you? I dunno if CD24 is too early or ok for you to test on, normally i just suck it up and wait for AF to show up (or not!) to test, but i know it does get tempting :P. If you do test now and get a BFN...i'm sure you wont be out of the race (just out of another HPT!

) and you can test again later or wait to see if AF shows! But a BFP would be amazing

it's a gamble!
