I’m 7w1d and I’ve been really anxious this pregnancy. My boobs aren’t as sore as they were when I was pregnant with my son and it’s hard to get through these first weeks before we get to see the baby via ultrasound. I have a Womb-Music non-invasive sound amplification device that I used with my Bose noise-cancelling headphones and I was able to find the heartbeat THREE times today! I’m so relieved. Just thought I’d share to let you know it is possible! It did take some patience to find it! Baby is implanted in my right side. I think you can buy the device on amazon if you’re interested.
