first time mommy 5wk 6 days

Hey all! I am a first time mommy and found out Friday that I was pregnant. I went straight to my gyno due to having PCOS and thinking it would take me longer to conceive. He said I was pregnant and 5weeks and 6 days today. I am so nervous and scared. Especially because my progesterone level was low. I'm taking oral progesterone now and hoping I caught it quick enough. I had been having mild cramping without bleeding. Is this normal? Any ache or pain my body makes I freak out, any other first time mommys the same?!? :)
