Help!

Shelby • Expecting baby number 2!
So I'm 5 weeks + 3 days. I haven't been to the doctor yet I go July 13. I've been having some heavy cramps on my left side no bleeding just cramping. Sometimes they come for a short amount if time and sometimes they are long. I didn't do this with my first pregnancy and I'ma nervous wreck right now... Can anyone help me.
