Hi Nelliesbelly
If you are at all concerned then it is a good idea to get things checked. To help you with the pain you can take Panadeine. They are a little stronget than panadol and are safe to take when pregnant. They may also help you sleep.
Are you taking raspberry leaf tea and evening primrose oil? They can help to bring on labour. Nipple stimulation is also helpful as is sex.
I hope things happen for you soon
