I think I might be pregnant. It's been a week since the condom broke. I missed my period.

Might be too early to tell. Or take a pregnancy test now

Takes about 2 weeks to become pregnant

Takes a bit of time to actually become pregnant, if your period doesn't show in 2 weeks, take a test

Ovulation ended 2 days before

Yeah takes a little more time because implantation still needs to occur. If you missed your period there could be a possibility you became pregnant last month but it wouldn't be from the condom breaking a week ago or your body could just be changing cycles, it happens :)
