What is this heartrate

Lauren 💙💜

Had a miscarriage in January and then 4 weeks ago I got 15 positive tests then negatives. Yesterday I could feel like little popping feelings in my stomach. On and off in and around the same spot. Used my fetal doppler just to see and found a heartrate of 110. Not sure if it's mine but is it common for women to have heartbeats in this area??? Just above pubic hairline.
