No problem. My friend actually had a baby after having tubes tied so i know it can happen lol
Yes there is still a small chance you could get pregnant. The best way to find out is to take a home pregnancy test after your missed period, if that says neg and you period doesn't come for another week take another. Or you could go to the doc and take a blood pregnancy test, it has to be about 8 to 10 days after ovulation for it to work.
