Just sticking my head in here because I well and truly qualify as a TWWer ... had my first day-5 blast transfer yesterday (seems like eons ago!). I'm was hoping that it would be a nice short TWW with 5 days of it happening IV but seems like it's going to last forever because my BT falls on a w'end and I'll have to wait to Monday for it!! I'm on crinone (and just one pregnyl jab day before ET), so I'm assuming that I should still be able to POAS because there'll only be progesterone in my system, no synthetic HCG??? Can anyone clarify that for me? Thanks in advance.
