29 weeks and weird cramping?

Kara

I'm 29 almost 30 weeks, and the last few days have had one-sided (always on the right) period like cramps, not like the all over tightening I've been getting with BH contractions, but slightly painful.

Is baby possibly hitting a nerve, or is this just cramping? It's not been frequent or anything, only happens a couple times a day tops, but the 'pain' I'm feeling with it has me slightly concerned.
