Yeah. At that ABV, unless you're using pond water (and maybe even if you were) you should still be fine. Just keep an eye on things and remember "Time will fix almost anything."
I've only managed to ruin a pair of batches once, and that was because I left them sit in the primary for 11 months. They were drinkable if they were cold and you'd already had a few pints, but I opted to dump them anyway. Yours should be fine, if a little flat. I wouldn't concern myself much with contamination in your case.
