HCG and Progestrone levels ladies!!!

I am 4 wks 4 days today and my HCG is 1059 and my progesterone is 15.7. The nurse said the doctor said my HCG was great but my progesterone was a little low, he wanted it at 17 so he called in a prescription for progesterone. I’m happy, but definitely a little anxious. The nurse said everything was just fine, but I can’t help but worry. I was on progesterone with my son (who is now 4) but I can’t remember what my number originally was with him. Has anyone else experienced this and everything turn out okay?
