So, I'll bullet point the recent past for ease 
age 50, in menopause
no hrt until a few months when I started using 1/2 - one swipe of gel
GP gave me wrong advice about taking progesterone so I haven't been taking enough
As a result I've got a womb scan booked to see if my lining has built up but GP thinks not
On Wednesday got what I thought was cystitis, given antibiotics which I started on Thursday. Also taking cranberry/granules/etc
Now feel like my entire torso is bloated, painful and cramping
My main question is: could this be related to antibiotics/cystitis (I haven't had it before) or could it be completely separate and related to now taking upped dose of progesterone - it's suddenly occurred to me that this feels a BIT like period cramps, but tbf it's been about 3 years.
I feel unwell, like shit, bloated and swollen. My GP has referred me for a scan in relation to the misinformation on the hormones, and they can't really do much more.
I haven't had any menopause issues otherwise.
Does this sound like something anyone else has experienced?
