You can get periods when pregnant,although it isnt that common,as your period arrived as usual i would say not,as for the breast and cramps, i get sore when im due about week before,and cramps,only way to tell is take a test.
you could be pregnant my sisiter had her periosd and she had a healthy veyr smart little girl. i would say take a test maybe a cheap dollar store test and then a more expensive test if the cheap comes out negative goodluck when is your next period due?
Im guess is no.But there is only a chance. Go and see your Ob. Good Luck
