Charting progesterone?

Does anyone have any idea whether charting my temps can indicate whether or not I’m getting enough progesterone? My current dose is 100 mg once at night and I’ve seen most others have a higher dose. I’m not getting it checked by blood work. Looking at my chart you can see when the progesterone supplementation kicked in and I got another temp rise. Whether or not it’s from the supplements, do you think this is a good sign that have have enough in my system to carry me through and maintain?
