FTM 30w+ question

Hello all! The past day or two i have been having really light, period like cramps. I use to never have cramps with my period except for a handful of times and they were stronger feeling than this. Anyhow, there is no consistency to when they come or go. I was initially thinking BH (i haven't experienced any yet that i know of) but my stomach never gets tight feeling in the least bit... at least not that i have noticed. Any ideas or advice?
