Hi Highlandgirl

from me too.
Sorry to hear you're still feeling rough.
Depending how long you have been without gel before restarting - it may be that you have increased too quickly. Some women absorb very effectively even from one pump and depending on your height/weight it may be that you do too though the spot blood test you had doesn't indicate that's the case.
You haven't said how old you are or where in menopause re cycles (before starting HRT), or how long you'd been on HRT before changing.... these all have a bearing on you might feel.
However I would go with it if you can, and see whether it settles, or can you reduce to say a pump and a half by discarding some, just so that you increase the dose very gradually to let your body acclimatise to the new dose before increasing again?
Sorry I can;t be of more help and hope you feel better soon!
