Hi, I am still trying to find a progesterone regime that I can live with. I'm on 75mcg patch. Oral utrogestan made me feel ill so I tried the vaginal route. It has been up and down - I used 100mg every night but after a while I had continuous spotting so I have had a 10 day break during which I had a proper period. Now back on it. So my question is for sequential utrogestan and a not too heavy period (I have very low ferritin), how many days per month should I take 100mg vaginally? Is 20 days a month ok, or could I take it for just half the month at this dose? Thanks
