Sara: so long as you took the test properly, at this stage of the game, there's earnestly no reason to be concerned you're pregnant.

With emergency contraception, it's normal to have both or either some menstrual cycle kookiness for a little while, and/or some unexplained vaginal bleeding. That bleeding might have been your period -- particularly if it arrived around the time your period normally would, or it might have been bleeding from the EC. Either way, given you a) took EC right away, b) used a condom and there was unlikely any failure and c) have a negative result with your pregnancy test taken two months after the fact, there's just no sound reason to be worried about this still.

Sounds to me like you likely did have a period, so it's not been seven weeks, maybe four at the most, right? If it hasn't been more than five weeks since the bleeding, I'd not consider you to have a late period just yet. Too, sometimes periods are missed or late for other reasons entirely: general illness, change in diet or exercise, and change in behaviours due to stress.

But certainly, if you like, you could see your sexual healthcare provider and ask for a test in their office. If you intend to keep having intercourse and feel really unsafe or worried about using condoms alone (they can be enormously effective when used properly, but some folks feel better about using two methods, which is obviously fine, and a great call if pregnancy is an absolute no-go for you), it'd be a good idea to go talk to them anyway about getting a second type of birth control to use as a backup method, and to find out what method is going to be best for you.
