baby shaking alot😳

Thalia • Baby #2🤗
Tomorrow ill be 34 weeks and for the past 2 days i been feeling my baby shaking inside and it last for more than a couple of seconds and no its not hiccups. I hope its not because i get scared every time my fiancé snores at night i mean he snores loud sounds like a bear 😒. So my heart rate goes up and i know hers too. Feels like shes having a seizure so i get up and walk around then she stops. Has anybody else had this before? The worst thing i can think of is her umbilical wrapped around her neck too😔.Â
