Aww mama, I understand the worry, HCG numbers can be so stressful to wait on! But really, you've made the right call waiting for your doctor's review, because HCG can be tricky and yours might still be progressing fine even if it's not exactly doubling. A few of us mum friends have gone through slower rises and everything turned out okay, but honestly every situation is different and that's exactly why your doctor needs to look at the full picture with you. Take a deep breath, you're doing everything right by getting checked. Hang in there!
