If you wait a week or so you should be able to find out wheather you'll have a normal period or it might not be comming take a pregnancy test your body might not have enough HCG levels to detect whether you're pregnant or not. I gave mine a week had light spotting went to the doctors and did a blood test found out I am pregnant! Good luck! Sometimes also you can ovulate 2 times in a month if your ovulation has been disturbed. I had spotted a whole 2 weeks because i was so stressed out and it was distributing my cycle! If you missed you period and it hasn't come within two weeks and a home pregnancy test isn't working go get a blood test much more accurate and you'd know for sure!
