Smelling off down there

My vagina doesn’t usually give off a smell. This past week I met a guy on my vacation trip to look for a place to live across the country. He was sweet and cool. He even hung out with my friend and her boyfriend at their place one night and that was attractive to me so I ended up doing the deed without a condom (yep I know the consequences... I have an iud and plan on getting tested ASAP). I noticed I smelled off after (he came in me) but figured it was just the cum. I wiped with some wipes after but didn’t shower until morning. Now it’s been almost two days and it still has a smell. No weird itching or discharge. What could it be? Did it really throw off my pH that bad? Infection? I feel like this is dumb to ask but I’ve never had such a smell after sex. I get my period tomorrow according to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> so I’m not sure that helps. Sorry this seems dumb. Any insight helps...
