Last Night of Stims???

So I went to the RE's today for my 3rd sono and bloodwork.  He said everything looked good (he didn't say how many follicles though). He said he wanted me to do one more night of meds (tonight), and I have to go back in tomorrow for another sono and some more bloodwork. He's hoping tonight will be my last night of meds, tomorrow I'll trigger, and then Wednesday I will be going in for my ER.  Fingers crossed.  I can't believe this is all happening!!!
