I'm finding sleeping on my side really hard-I'm a tummy sleeper normally. I've been lying on my side for the last 2weeks as bump is now stopping tummy sleeping and I've read that lying on your back - the only other comfortable position- is bad for baby and me. I'm waking up several times a night with pain in my mid back, where the arch is. Any suggestions? I'm sleeping in a semi foetal position, which is also giving me pins and needles in my arm!
