Hi!
The progesterone is probably the culprit. It is common to retain water while taking it, and it also causes mood swings and headaches. If you were my patient, I would try a cycle without the progesterone added. I would have you take the Femara on days 3-7 and then check your progesterone level on cycle day 21. If your natural level is fine, there is no need to supplement during the second half of the cycle. I would probably supplement with progesterone if you had a positive pregnancy test though.
Also, you may wish to consider trying Metformin together with the Femara. Studies indicate a slightly higher pregnancy rate with the combination of the two.
Good luck!
