I posted a couple of months ago re the breakthrough bleeding I was having. I'm 66,have a Mirena fitted and use Oestogel but was experiencing some fairly regular,roughly every 4/5 weeks bleeding,well pinky discharge really, and asked for opinions. I've been on this regime for about a year and thought it should be calmed down. I was using one pump a day and someone suggested increasing the dosage slightly. I tried one and a little bit which had no effect so I now use 1 and a half(ish) and so far so good. I missed a day recently and had some spotting for a couple of days so used 2 pumps to get me back in track and then went back to 1 and a half. I know at my age I don't need big doses of oestrogen so it's a bit trial and error but the point to all this is, sometimes you just need to see what is best for your body.
