Thanks Katherine, worth knowing, especially as I have a box of tests now
and AutumnWalks I kind of understand what you're saying as I've had a number of bouts of diarrhoea since 2020, it seemed to always precede a chest infection or covid (we weren't sure which in the beginning without the tests) but I still don't know if the hrt (started around then) made me susceptible to it as before then I never had it. So yeah, I wonder about that, probably partly why I'm wondering about covid, as I would rather it had an explanation. But covid is here to stay, if its that I just hope I gradually lose that symptom!
