I'm about 18.5 weeks preg with my first. Occasionally I get pains, like cramps. Just like period pain. I know some pain is normal because u are growing. But last night I was walking around the shopping centre for quite a while and got horrible sharp pains in my stomach, in the left side. They almost took my breath away and lasted about half an hour. After sitting down in the car on the ride home for 20mins i was better.

My question is How are you supposed to know what pains are normal and what pains to be concerned about?????????????
Anyone else have pain on one side???
