Hi Danyelle, it was standard practice for my clinic to check my progesterone levels several times in the TWW. I was on injections through my IUIs and Progesterone pesseries through IVF. My clinic told me that anything over 30 is good but the usually liked to see me a little higher. Through out my IVF cycles my prog always seem to come in around 60-80. We finally got our BFP in October and I didn't really have any symptoms either until the very end. I didn't suffer nausea till week 8 and my first symptom was when my boobs started to ache about a day before my period was due. Good luck with everything. My fingers are crossed for you. Try to stay positive as everyone is different and no symptoms does not necessarily mean things aren't working.
