Has anyone else had to take progesterone during pregnancy before? I'm on my 10th pregnancy, with one living child and 9 miscarriages and my doctor thinks I have Low progesterone which has caused my miscarriages. I am waiting for a gynaecologist appointment for next week to be tested and start on progesterone but I'm worried-my last miscarriage was at 4w2d and I'm 4w1d today with severe migraines and dizziness. Feeling hopeless.
