I got what i think was my period for 1 day, 2 days ago(it was about a week early and kinda heavy for that one day). Then it stopped and I have been having some very light spotting and cramping since. I always have my period for 4-5 days. I did have unproteted sex about a week ago. I just want to know if you think i could be pregnant and when should i do a home test?
