think of it this way a lot of us have what's called implantation failure (me included) the thinking behind this is that the timing is off that the lining is ahead of the embies....so by them leaving some eggs your body gets to time everything
ok your little ones are in the dish doing the dance with hubby's swimmers...your remaining eggs are being released by your body one of those has to start down your newly opened tube so that's making its way down over the next couple of days your body doesn't know it hasn't been fertilized so as its traveling your other little ones are getting ready to come home...as your egg reaches your womb your body will be all triggered to receive it only tada the dr switches it with your embies
perfect timing ... sending love i hope you don't have to much pain or discomfort
love Aunty

He sends you his best regards as he thinks that you have helped me calm down.
I have been to bed for a couple of hours. Read all you posts. Feel better already. PMA somewhat back on track. Trying to be glass half full rather than glass half empty 
). I have had poor response, and poor quality embryos. So my RE is wanting to do 3 stim/ERs in a row w/ new protocol. All ferts will be frozen after each ER. After the last ER, will plan a FET (thaw all at same time---hopefully around 20), hoping to have a few good ones and have my uterine lining primed and ready for action 
not long and we'll all have our dreams come true...literally!
