Me n my boyfriend had sex on the 15th of August he wore a condom but when we were done we noticed the condom broke my period was due on the 3rd I didn't get it till exactly a week later could I be pregnant

You could take a HPT and do more than guess.

If you got your period then it's unlikely that you're pregnant, even if the period was late.

If you're worried about pregnancy then try a pregnancy test using first morning urine.

You should know that pregnancy is possible any time you have sex, even if you use protection correctly. If you're not ready for a child, then you're not ready for sex.

Agree, if you got your normal period most likely you are not pregnant.
