Is this your first? You may be experiencing round ligament pain and just assuming they are contractions.....right around where you are in your pregnancy the ligaments and muscles on the sides and front of your stomach are being stretched to their limits and you'll experience pains that almost feel similiar.....you can also be experiencing braxton hicks contractions, which are your bodies normal way of getting ready for the real thing. If it was serious and you were going into pre-mature labor they would be pretty regular and closer together, not a few random ones during the day!
