Fetal Doppler

Layla • ✨I`m 23,Married for✨ 3yrs,miscarriage at 3 months Dec. 2013 & now happily expecting a baby in January!✨
I'm thinking about getting fetal Doppler for peace of mind. I had a miscarriage in December so I'm a little nervous about this pregnancy
​ If you have use one,how early was ur pregnancy when u detected a heartbeat? :)
