37.5mcg is such a low dose of estrogen that SOME private specialists would allow this without progestogen.
I have never encountered this before - would this be regularly on NHS? I wouldn't say it "is such a low dose" though I see it is classed as low. Nevertheless we haven't heard of women using a patch of this strength without progesterone maybe except in very exceptional circumstances of extreme progesterone intolerance (there was ONE woman on here some years ago) but in such cases would be monitored very closely with regular scans, on NHS, as she was (Panay's clinic).
For example even with the Menostar - which was and maybe still is available in US, at 14 mcg, which was recommended to be used generally without progestogen, an annual course of progestogen was advised.
I do agree that a lower dose of progestogen may be fine and alternate day vaginally may be sufficient though you won't know without a scan.
Incidentally if you have poor bone density., 37.5 mcg is not licensed for protection against osteoporosis, the minimum being 50 mcg, though some oestrogen is better than none, so I would suggest you ask for your estradiol levels to be checked for this reason. If they turn out not to be sufficient then I would urge you to do all you can to try to attain the level needed and see if your doctor will work with you to enable off-licence regimes (of progestogen) to be used with regular scans in order for you to get maximum protection?
Your painful breasts and weight gain (bloating) could also be due to progesterone because you are taking it continuously?
