Frequent pinching around pelvic area?

Amber • Mommy to Bryce 12/2/14. Baby #2 arriving May 2017!
Its probably nothing & I'm making more of it than what it is, but ever since 1 dpo (currently 7dpo) I've been having brief but frequent pinching where I think my ovaries are. It will happen to both sides but at different times. Any one have something similar? Is this a good sign or no sign at all?
