Yes it definitely will raise your temps. I take progesterone three days after a sustained thermal shift so that I know that I ovulated. Also, that's the way that my dr said to anyway. If it is taking to early it can inhibit implantation. Also, depending on how you take it orally or vaginally, it will mimic the signs of pregnancy. This last cycle I took it vaginally and the symptons were a lot less. I continue the progesterone until I get a temp dip and take a HPT. HTH
I am attaching my FF chart so that you can see the difference. I took progesterone Oct and Nov.
