I would think that you should be on a sequi HRT. You seem very young to have a continuous one. This happened to me and quite a few ladies on here as GP's can often make a mistake. I think you should query this.
Info on Femseven Conti "FemSeven conti is known as a continuous form of combined HRT. This means that each FemSeven conti patch contains both estradiol hemihydrate and levonorgestrel, so that both hormones are received each day. The patches release the hormones through the skin into the bloodstream at a constant rate and are designed to be changed once a week, ie a patch is worn for seven days and then replaced with a new one. This type of HRT does not produce a monthly period, and so is most suitable for women whose periods have already stopped, ie for postmenopausal women"
