Hey there Hon
Why dont you just give your carer a call and seek some advice on the phone- perhaps she may have a better idea

could they be BH? Have you tried having a lay down or a warm bath- maybe that will help.
or even some panadol if you are so inclined to do so

i got BH from about 15 weeks with my twins and have felt some little BH allready i think- the belly tightening and oooh for a sec- the settle if i stop!

if you are still worried , but cant get checked out today- perhaps you can go in tommorow and get checked out

i am sure someone like Scmickers or Alan might be able to help you more

hang in there
