my period is two weeks late and i had 2 days of spotting around the time i was suppose to get my period but it was really light pink and i didnt use a pad or tampon...there was barely anything there. I also ovulated late and had intercourse without anytpye of protection. Now today i started spotting a little its more redish now. Can this be a late period or pregnancy? ive also been feeling sick around certain things and smells and have been getting constant headaches and back aches
