thanks everyone - I think I'll keep things to myself for the forseeable on account that my dad clearly doesn't approve and any time I speak about it to my mother, I'm met with "well, you must lose weight first as they won't take you seriously" and variations of that message 
it does my head in! it isn't as easy as "lose weight, find a man, then have babies" as my mother wants, any more - especially as I've just spent 14 years on a road to training in my career and have only just succeeded so am not likely to want to give up work forever! (mother was SAHM and so is sister - they think little of working mothers ... sigh)
Not only that, of course, but its not like if I "found" a "bloke" that I'd want to "have his babies" immediately anyway! Geez, I think my whole family live in the 50s

thanks for the support - let's hope you're all still here in 2/3 years when you've all been successful and I'll be starting out!
