Is anyone else coming off of progesterone and estrogen?

12 weeks, 1 day with luteal phase deficiency. Six miscarriages and no children. I've been on oral and vaginal progetesrone 3 x daily and oral estrogen too since I ovulated last. Today is my first day off the meds as doc wants to test my levels without them in 3 days at Ultrasound to assess if placenta is working. Anyone else experience this? I feel incredibly nauseated. Any other symptoms to look out for?
