I'm 17 weeks pregnant and suffering with the following: terrible knee pain due to sudden weight increase (i look 6 months rather than 4 months pregnant)

Headaches.
Sinus Ache.
Nose Bleeds.
Neck pain (nape) when I sit for prolonged periods looking slightly downwards.

Surely a pack of panadol a day (nearly) is way too much for me to be taking with a baby in the belly? >:(
