I agree with what's being said, you need to get the test and then wait to see if you are getting a period or not (and do another test if the one you got is negative). You don't need to worry about whether or not your boyfriend will want the baby when there might not be a baby to worry about. And then I guess you will have to think about whether what you want is compatible with him, because if you want the potential baby, and he doesn't you should start thinking about whether you really want him to be your boyfriend. Just because he fathered it doesn't mean he has to be involved (you can just call him the "sperm donor"), but again, there is no cause to worry, so I REALLY don't even need to be saying that.
