On my 8th cycle, I did a HPT on 11dpo, waited over an hour but still -ve. Didn't bother with another one coz I'd had 7 previous cycles of -ve HPTs which then resulted in -ve BTs.

However, that cycle, on 13dpo, my beta came back +ve, which went on to be a healthy, trouble free pg!

There was another member who was cycling with me who had a -ve HPT on the same day as she got a +ve beta!
