Progesterone level

Jenn

I received my HCG level yesterday of 21 and today my progesterone level results that are 3.2. My last cycle was March 25, making me around 3wks pregnancy according to my OB. We struggle from infertility so I’m extremely worried. I never had blood work with my other children this early on. I did have some spotting for 3 days (only when I wipe) but has since stopped...are these normal for being 3wks or should I be worried.
