Yea I'd say wait to take another test, at least until your late.
I did take a test but I think it's too early still. I'm not supposed to have my period for another week but just wanted to see if the cramping was something other people got. I usually only have cramping the day before my period starts.
Could be pre period cramps, I would get them about a week before mine started and I'd be real sickly and moody. My major indication was sore breasts before my missed period. If your late you should take a test though
Did you miss your period ? Take a test.
