1st time pregnancy requirement to know if this is regular...?

Ok ladies I need a little help...

This is my first pregnancy, so I am not sure what is regular and what isn't.
AF is scheduled to visit tomorrow, but I have be having cramps off and on since last Friday. I took a HPT on Sat and it be BFP I took another one on Monday and same thing. Are these cramps normal? I read somewhere where 2 to 3 days is everyday, but I have been having them stale and on since Friday.
Thanks =)
Answers:    yea that normal.I had cramps off and on i thought i be going to start my period but never did.when you go to the doctor they explain stuff like that to ya..
i forgot the quantifiable name for it but it is normal it is just your uterus growing trying to accommodate your little one inside
