PCOS and progesterone cream. help!

Christina
So I started using progesterone cream this month to see if it would help steady my temperature after ovulation. I have PCOS. For those that use it and take your BBT have you noticed a continual rise in temp till you get your period or stop taking it?  My BBT has been increasing and I know with women that don't have PCOS that can be a good sign of pregnancy. Thanks.
