abdominal pain on right side

Zoe

Just come into my 12 weeks I started feeling a slight pulling/stretching feeling in my lower abdomen. It was quite painful it woke me during the night and only lasted a little while, but wanted to know if this is normal? Is it my uterus just growing and my ligaments stretching? It only happened last night and I feel little bit this morning, it's a really weird feeling. Am I ok?
