Pangs and pinching feeling 17 weeks?

[Aismixx]

I have been feeling flutters, tickles and tumbles.

But in the last few days a have been feeling what I keep describing as 'pangs' but no one can seem to relate.

They aren't exactly painful but it's like a pinching nipping feeling? Anyone any idea what this is?

Feeling is in lower stomach btw.
Not a crappy/implant feeling.
