I'm 14 & I had sex on the 9th & I ended my period on the 7th & the condom broke & he had sperm on his penis but just a little bit. I'm worried that I could be pregnant? & I'm also on a birth control pill, Ortho Tri-Cyclen Lo.

If you have been taking the pill regularly, and on time, without missing any, you would be pretty safe. However, no birth control will be 100% effective so pregnancy will always be a possibility, even if the chance is small.

Timing wise it would put you at a greater likelihood, but again, odds are small with protection being used properly.

You will need to wait at least until you are closer to when you would expect your next period to try a pregnancy test. Best to wait until you actually see if your period is late as that tends to allow for better accuracy.

Just have to say, I do hope you would reconsider having sex at 14 as obviously you would not be in a position to support and raise a baby if you did indeed become pregnant. Not to mention the potential health risks to you and a baby if you became pregnant so young.

With that being said... at least you are using two forms of protection and that is very wise.
