Just turn 17 weeks today. And yesterday and the past weeks when I have woken up I could see a bump. Not so big but its noticeable is there at least for me. But today when I woke that bump has disappeared! My low back been hurting and I have been feeling pinches.

Should I be worried? Or can it be possible that my baby is not laying in front. I don't i know its my first pregnancy.
