I am doing exactly the same thing muzzy. There are suggestions that 4dp5dt should be good enough for HPT. I am so tempted. This is my first time. It has been 6dp5dt now for me. Not sure if I can still wait until next Thursday for BT. I guess I'm worried finding out myself and create more anxiety on whether the HPT is accurate or not. Seriously, I'm going insane!
muzzy, did you POAS in your previous cycles? If so, when did you do it?
