Since this just happened yesterday, considering abortion when emergency contraception is available is pretty short-sighted.
The MAP costs around $25. Abortions start in the hundreds of dollars. The MAP isn't something you have to wait for and can PREVENT pregnancy from occurring, rather than having an abortion well after it does. The MAP is far less involved, carries no risks, requires no recuperation time (because to be honest, you will need to rest after an abortion, and be prepared, just in case, for returning to the clinic or a doctor should you end up having heavy bleeding or cramping afterwards, so having it be a secret isn't generally a good idea), and it's easy to obtain, as well as HIGHLY effective.
Yes, you have a risk of pregnancy. So, within the next two days, get yourself to a doctor or clinic and ask for emergency contraception.
FYI, in the future, condom breakage is VERY unlikely to happen if condoms are used correctly, namely, with enough room being left in the tip, and plenty of latex-safe lubricant used with the condom.
