OK, weird one.
I'm bloated. I noticed today. In fact, I look pregnant. I'm not svelte at the best of times but usually manage to hold it all together. However, today I look positively pregnant and am bloated. I've never been bloated before, so I have no idea what could be causing it.
I'm eating the same sorts of things I usually eat. I don't drink alcohol, I do drink coffee but only in the morning.
Any ideas?
