after stopping progesterone and Estrogen (IVF meds)

Ashley • Happily married for 3 years. 2 angel babies. Our 1st FET = BFN. 2nd FET = BFP! Expecting our miracle September 2017!
My doc gave me the OK to stop the progesterone supp and IM shot and Estrogen Patches this past Saturday cuz I am now 10 weeks. I thought I was going to feel better (with the nausea), but I only feel like I am doing worse. I am vomiting more than I was and at times I feel like I am going to pass out (almost like my blood sugar is low - shaky, etc). I am just wondering if my body was so use to the hormones and now I stopped, is my body adjusting and that's why I feel so awful or if it's just first trimester stuff .
Did anyone else feel worse before they felt better after stopping the extra hormones ?!
