betty, I would get it from time to time as the end of my pg's got nearer too. It is also entirely possible that you are beginning pre-labour and this can usually start from now and last until you give birth (which isn't what you want to hear probably). But it all helps towards the end goal of giving birth to your baby too OK, by giving your body time to prepare for the big event by gently stretching and moving everything into place for it.
