My boyfriend and I had sex on June 29. He had a condom on and I used a cervical sponge that contained spermicide. After he ejaculated inside of me, we realized that the condom broke and immediately got the Plan B pill. About five days after that, I had a heavy period that lasted 6-7 days, like a regular period. I typically have irregular periods to begin with, but it's been almost 6 weeks since the incident and my period hasn't come yet. I'm experiencing sore breasts like I usually do before a period, but other than that, nothing.

Could I be pregnant? I'm really not sure and it's stressing me out. I know that can delay your period but I really can't stop worrying now.
