Hi nicole,

yes it is very normal to have cramping at 18 weeks. I had cramping that started about then, and everytime I got out of bed, my stomach cramped. I'm 32 weeks now, and I have started to get cramping in my calf muscles aswell. I haven't been told that sleeping on your back can cause any harm to bubby, my doctor did mention that sleeping on the back can become uncomfortable, as the baby is lying on your organs. I find that lying on my side is actually much more comfortable.

As for the removal of an ovary, I truly don't know if that would be a cause to have a c - section, that is something you would need to speak to your doctor about. I can't imagine you would need c - section because of the scar it left.

Good luck with your pregnancy.

You are not supposed to sleep on your back because it is bad for circulation. The baby's and yours.....And plus the baby could be lying on the sciatic nerve which could cause pain for you.

Thanks for all the replies.

don't worry about the cramp, and don't worry about sleeping on your back. If it gets uncomfortable you will naturally turn over in your sleep. You need all your energy for the pregnancy, not worrying about how you sleep! The person who last gave you advice is only fourteen, so be careful who's advice you listen to.

Who is 14 ? I missed something. I been getting sciatica sometimes later at night when i'm cooking dinner, or after i've been on my feet for a while. I hope it goes away after this pregnancy, it is so painful I nearly jump out of my skin when the nerve grabs.
