I think, if you are concerned, you should go to your hospital and get checked out. They are there to look after you and your baby throughout your pregnancy not just for the birth of the baby.
Don't do the "wait and see" approach because you would kick yourself if something happens and you didn't get checked out.

No scare tactics here hun, but I live by a motto when I am pregnant "If in doubt, get checked out" your care providers have a job to do and so do you. Their job is to ensure your pregnancy goes as smoothly as possible and to look after you when you give birth. YOUR job is to grow a baby and look after yourself and raise any concerns you have with your care providers.

good luck hun
