if i were you i would go to the gynae...you might be pregnant!my friend had her first month period as normal as ever and she had 4 weeks pregnancy!goodluck :)
Period seemed normal maybe a bit lighter but not much same length but my stomach just feels weird now I can't explain it
Did the period seem normal as far as the length and the flow? If it seemed different (lighter and shorter), then it might have been implantation bleeding. Nausea, sore bbs, and mood swings could definitely be signs of pregnancy, too. You probably should do a HPT to be sure. Good luck! :)
