I'm 13 weeks and my doctor didn't even attempt to hear the heart beat at my appointment when I was already 12 weeks 6 days. And I have to wait for a referral for a sonogram. Which can take weeks and I leave for Hawaii in about a week and a half. I'm super anxious and impatient. I was just thinking of taking matters into my own hands. But I am most certain that this will be my last baby, so would it be waste of money and pointless?
