Increased Progesterone prescription

my midwife increased my progesterone prescription last Thursday. I was taking 100mg every night and now I take 200mg in the morning and at night. she said my level was at a 10 and wants it at a 20 to build a healthy placenta and will check the levels to start weaning me off the medication by week 14 I'm 10wk&1d today. hoping baby stays healthy and strong.
