Ovulation test. Too soon?

OK. So I've been been TTC my fiance has come into town from the army for a thanksgiving break. My fertile window started Tuesday and ends Monday. So far we have "done the deed" twice. Once Tuesday night and twice thanksgiving. I'm pretty sure we will again tonight. I just took a ovulation test and there is a faint line like my ovulation is close. Is there still a chance for me to get pregnant.
