Is it suppose to hurt?

Ashlee • R.I.P my little angel 4-8-2016 💕 Welcome to the world Aria, our Rainbow baby 🌈🍼 Esthetician💄
Help! So im 22 weeks and usually when im laying down for bed and feeling the baby kick it dosnt hurt like EVER.
But tonight im having cramps and pulling, even when she kicks and im not sure if this is normal 😢 maybe its the way she's laying ? Ive been tossing and turning and the next minute it hurts again!
