How does it really feel to have contractions?

Everyday I ask myself the same questions "How does it really feel to have contractions? Will I ever not noticed that that pain is contraction?" 

The reason why I'm not sure is because I feel pain at my tummy area everyday. I wonder if those pain will mask out my contraction pain... 

Anyway, I guess I just need to trust God that He knows best and He will tell me when it is time. It's a waiting game now.
