Canīt offer you any more advice hun, because to be honest I donīt really understand all the various different hptīs. Iīm keeping everything crossed for you that the doesnīt get you this month and you get your dec bfp.
Dont give up yet, its early days, the digi test sounds quite powerfull, the ordinary pt normally only work at about 4 days before af, and generally thats only bout50% accurate so theres still hope, much love xx
