Uncomfortable and can’t sleep

I’m currently only 7 weeks and a couple days but I haven’t been able to sleep since like 6 weeks , my body hurts so bad . Before pregnancy I was fine . I can’t sleep with my pillow , my back and neck are aching . & I’m waking up every 2 hours . Please help .. with my son I was the opposite and slept way too much lol . Also I am exhausted !! I have a toddler & I’m a sahm plus getting no sleep ☹️. Ideas on how to cope ??
