Me and my boyfriend have been trying to get pregnant. my period was a day late with light brown blood, then the next day vary watery.

Pregnancy test: From what you say you may have had a menstrual period -- and that would eliminate pregnancy as a possibility. If you're unsure about this, home pregnancy tests are inexpensive and available at drug stores. Hoping you and your boyfriend plan on staying together for at least 20+ years, if you're wanting to bring a child into the world. Best wishes.
