What is it?

I was at 26 weeks day 6 (ystrday) when i had "stitches". You know, the stinging pain when you run or walk alot or after run. It's like come and go. The pain is at my lower stomach. I had it 4 times. Came and stayed for like a good 5 mins, and then gone for 2 mins. Then it came again. Total 4 times before i lay down and fell asleep crying. When i woke up, it was gone. And today, i feel like having diarrhoea, but only toilet 2 times. But the stomach pain is like twirling in my stomach. Is it braxton hicks? Im scared it's contractions as it's still early to have it?
