Worried @11w after progesterone stopped

G
I just went off progesterone at the completion of 10weeks per my doctors advice. While it's a great feeling to be off the slimy stuff, I'm also feeling nervous about miscarrying. I haven't miscarried before and this is my second pregnancy after a gap of 5 years and first round of <a href="https://glowing.com/glow-fertility-program">iui</a>. It is freaking me out so much that I'm scared to go for my usual (3 days a week) walk on the treadmill for 30mins Anyone else in the same boat?
