So far in T3 I've had:

Swollen Fingers
Higher Blood Pressure (but still very normal)
Can't walk long distances
Reflux/very slight nausea
Back Pain/starting the return of Sciatica
Tiredness
Insomnia
Nasal congestion (but it is winter - probably just a cold)
Memory Loss
Colostrum

Also I'm very easily distracted by the kicking baby and am seriously peed off about "not looking pregnant" (yup, the hormones are back in force)! I can still lie comfortably on my back, although I try to avoid that, and can lie on my tummy too when I have to. All this by 30w!
