Weight gain - please tell me this isnt too much...!!?

Hi there

Im 29 +1 weeks with my second, and since the other day when I weighted myself on my MIL scales (I dont have any at home loL!) and realised ive put on 2 stone already - im a little bit freaked out and concerned that this is too much...
Im 5"9 (so quite tall) and was about 10 st 7 before I got pg.
it was 7 years ago when I was last pregnant so cant remember exactly how much I put on then but i think it was about 2.5 stone in total.

Im lookin gor some reassurance that im not gaining too much wiehgt ( i dont likk like ive gained much anywhere except bump, thighs and boobs lol.....) so if thats the case it means my baby is getting very big!! my son was big (9lb 4) so i always knew this one wasnt going to be small either but even so!!
The MW said I was measuring a week big for dates and then yesterday when I was in labour ward having a trace (he stopped moving the last 3 or 4 days - another story!) they measured me again and I was measuring 2 weeks big for dates........

Im starrting to worry ive got a gaint baby in there already - help.....,.

ps had a couple of dizzy/funny turns a couple of weeks gao and mw sent me home for a ocuple of days rest off work as bp was raised (only slightly - not into "high territory - but high for me) and now im worrying that the weight gain has somethign to do with the bp too...
As you can tell im winding myself up about this and need some reassurance!!
Thanks in advaance
