Ok this is an odd one, bear with me.
Ive had horrific sickness with this pg (dc3). Not HG, but not normal m.s either. Anyway, aside from the usual smells and food setting me off, (anything except mashed potatoes and coke, pretty much) particular "things" or even thinking about certain things sets me off too.
Totally random.. e.g. particular sets of cutlery (that had been my favourite), certain rooms in the house, and clothing. Even thinking about it now I'm heaving and retching. 
So, now we all know I'm an odd ball...
I can't bear anything vaguely tight on bump. Couldn't even in previous normal sickness pg. HAS to be under. I am currently 12+4 and living in three pairs of trousers... a pair of low cut non mat jeans, a pair of dh pj bottoms and a pair of dh trackies... I only look vaguely respectable in the jeans. The rest of the time i look like I've just rolled out of bed..
I'm going to have to bite the bullet and get at least one more pair of bottoms. Ideally soft, stretchy jegging type things. But even looking online at them (and thinking about it while writing this) makes me heave, retch and if I don't stop, vom.
To save me taking ages and feeling horrific trawling through sites, can anyone post any links to pairs they'd recommend, pls? Ideally a decent amount of elastic in so you don't get a saggy bum/knees by the end of the day. I usually wear a size 12.
Thank you a million
