Could anyone help please?
I bought a cbd fm last month and have begun using it this month. Am on cd 6 so should begin testing today, up until now it's been working fine - pressing the 'm' button and setting the cycle day etc. This morning when I turn it on the exclamation mark and clean symbol are coming on, so I've cleaned it with a cotton bud and water and left it to dry (didn't actually make it that wet tbh), but it's still not turning on properly and keeps coming up with the same symbols.
Any advice please? Thanks :)
