Ill try the pillow when sleeping and ive also found a bath helps with the headached and back ache ... as for the cramps im getting to endure them now ... ueah I agree best yo stay off medication and painkillers when pregnant especially in my warly stages ...
The only think i can suggest is for your back. You can try sleeping on your side with a pillow. I lay with one leg strait and one leg bent and the pillow under the bent one. As soon as my back started hurting i did that and havent had any back pain what so ever since and i am 38 weeks now. My back hurt so bad through my whole first preg, i wish i knew about the pillow then! At first i just used a reg pillow bc the body pillow was too big and made my back hurt but when i got bigger i switched to the body pillow. I dont have anything for the head except try a cold rag over your forhead and eyes i did that for a little bit and it helped but if it doesnt then try a low dose of tylenal but just try to go as long as you can without taking it just so you arnt taking a lot of meds while preg. They say it is safe but i would only do it in moderation
