its normal to get cramping early in pregnancy. So much so, u are so sure AF is on her way. Most of the time its not. If the pain is getting unbearable and/or is accompained (sp) by blood, go to the hospital to get checked out.
Increased mucous is common in pregnancy, but if it gets smelly or itchy go see you GP as it could mean an infection which are also quite common in pregnancy.

Try and relax, i know its hard... remember we are all here for u, and welcome!
