My last period only lasted one day. How many days later would I be ovulating? The condom broke when I had sex and I don't want a pregnancy scare.

Pregnancy. This sounds odd unless it has happened to you before up to 50 percent of pregnancies result in miscarriages and the woman thought it was a weird period however it also mean inplantation of the embryo and you could in fact be pregnant, take a pregnancy test.
