I"m guessing your symptoms are caused by the progesterone levels...thats really good if your progesterone levels are high! Yeah..too early for prego symptoms.
When I did IUI, they started me the night after on the prometrium suppositorties. It is to help get that lining in your uterus niice and thick for implantation. BUT if they said your levels are good... I am not sure. hmmm. I would call and ask to speak to your RE again and tell them you are thinking of using it, would it hurt?
The trigger shot is the same chemical that the placenta produces when pg, Hcg. It can cause many of the same symptoms as pg. It will also cause a positive hpt until it leaves your system.
Thanks Tina...that is one powerful shot. ;o) I didn't know all this came about from the shot..boy have I been dreaming for all the wrong reasons. ;o)
If you did IUI on Friday, it would be too early for implant to have occured and be having symptoms from it. The "fullness" is more likely from the trigger shot. I hope it takes!
