So I had one of these for my first pregnancy & never got rid of it. Decided to mess around with it to see if I could find my jellybeans heartbeat. According to a bunch of apps (including this one) it says I should be 8w1d definitely wasn't expecting to find it! So maybe I'm a little farther along? It was super hard to find & very faint but very strong! I kept finding my heartbeat at first & as soon as I was about to give up we heard it! My first appointment isn't until Wednesday so I've been stressing hoping things are okay with my jellybean. So hearing it's heartbeat made my heart melt as well as my fiancés. These things are awesome! So glad I didn't get rid of it 😍
