Hi Keohane 1,
If it's giving you unbearable side-effects then it's best to stop taking it and switch to something else.
I'm not on HRT as I don't want any side-effects of all sorts. This kind of progesterone can only be artificial as it's not produced by the body. It would be much better, for those of us who still have a womb, if we did not have to take progesterone.
