I started taking progesterone for a few weeks before my period. my mental health seemed to benefit from it. would it effect concentration and mental ability? I would like to get on it all month if that is possible, but do not know if thats ok. I also have recently been put on an antidepressant. this has helped, but the progesterone seemed to really help my ability to read a retain things, i have always had a hard time concentrating and keeping mentally awake and aware. adhd i think, but the minute i went off of it i went back slightly.
