Finally heard the heart beat at home!

A few weeks ago I posted how my doctor said I'm either not as far a long as my last period says, or I'm gonna miscarry. Well I've had morning sickness almost every day. Sore boobs/nipples almost all the time. I have never bled at all. I never once thought I was miscarry. In my heart I just felt like I wasn't as far a long. Well I have a home doppler and I've been using it a couple times a week since finding out and haven't been successful. Last night I tried again and after a few minutes I heard the thumps of a tiny heartbeat! I started bawling. Baby is growing! I go to the doctor Jan 9th and now I can't wait. I'll get another ultrasound and finally find out how far I actually am. I ended up losing the heart beat and tried again a couple hours later. Again after a few minutes of searching I finally found it and my boyfriend was able to hear it this time. It was so sweet. I also managed to record it so I keep listening to it over and over. I'm so in awe. This is our rainbow baby after the loss of our 6 month old daughter in August. Praying for a healthy baby and delivery.
