I was recently diagnosed as perimenopausal after going to gp for hrt for mood swings fatigue and brain fog. I was sent for blood tests to confirm. I was told to try black cohosh which I did with no effect for about 4 months I returned for hrt again sent for more blood tests which showed estradiol OK vit d low so went back for these results and I've been given vit d and sertraline. Ive been told that hrt is for hot flushes and if I get them to return sertraline will help with mood swings and vit d with fatigue does this sound right?
