my embies were day 5 blastocysts. i had one (perfect something or other blast) put in and 4 beautiful morula blasts on ice. i am extremely short tempered today (which is how i am before AF) and have twinges in my tummy almost constantly. but i had no mood swings whilst doing all the drugs etc over 6weeks so maybe its just my hormones adjusting to the change. GAWD this is so scary exciting and confusing all at once!
