Unprotected sex with my boyfriend Wednesday. I took the morning after pill 18 and a half hours later. My period is 3 days late. What are the chances?

Unlikely. It sounds like you had intercourse very close to your expected period time and you took Plan B at a good time, so it is unlikely but not impossible. Wait a few more days and if no period then perform a pregnancy test.

Late periods. It depends on how old you are or if you have had intercourse within the "danger" period, but missed periods for females almost always warrant a pregnancy test. Spotting can also mean hormonal changes which may be natural as you age, or related to a number of other factors, including stress, nutritional variation, anemia, etc. Recommend you visit an MD clinic to be checked out.
