welcome to hcm
thanks for the query
since your periods came recently there is negligible chance of getting pregnancy
is it spotting? or the period continued 3 to 4 days like normal one?
if you are pregnant then your period will not come. but you got it but bit early.
if you still have doubt then you can confirm i by urinary hcg
test. its very simple one . you can do it your own in home by kits available in market
