Right - i'm 8+5 and this is my 4th child.
So i've done this before - but ... last time was 11 years ago!
Now, i do not remember feeling this 'full' at this point with my others. I think i feel more like 4 months. Boobs are as i would expect, like pre period - bit tender when the bra comes off at night, and 2 cup sizes bigger already. 
No MS, but VERY VERY tired all the time. Raging hunger - but cant eat much before feeling uky.
So - my question is - can anyone who has had a single birth and a multiple birth describe any symptom differences during the first trimesters.
Can anyone in fact who has had twins tell me any specific symptoms?
My partner says i'm being paranoid! I do have a fear of having twins - but i've only been thinking about it since i felt so very 'over full' and tender in the tum. It even feels uncomfy to bend over to pick things up for goodness sake
