Yikes! Cramp-ish feeling!

Marah • Play nice.
So I'm only 7w and this is all new to me.
I keep getting this uncomfortable feeling..  
It's not painful and doesn't feel like period cramps.
More like an awkward pressure or pulling  sensation. 
And it is driving me nuts! 
Anyone know what I'm talking about?
I know cramping is pretty normal.. Is this what pregnancy cramping feels like? 
Do I have any reason to worry? 
I'm letting anxiety about a past miscarriage get the better of me. 😕
