Well I come to find out, via google, that taking progesterone can delay AF even when not PG. I don't think I'm PG:( But RE wants me to continue the progesterone til Saturday if no AF. If on Saturday I test negative and no AF I am to stop the progesterone. I've have super small glimmer of hope that I'm PG so I am ready to move onto the next cycle.
Re: CD 28, BFN, no AF...arghhhhh.
Today (1/29)...BFN...no AF. If I get another BFN tomorrow (which I'm sure I will) then I stop the progesterone and wait for AF to show up. So wierd I NEVER go past 28 days (except when I m/c'd).
