Help?

I had sex around 10-11am.

He came in me, (yes, I am on birth control) afterwards I cleaned with a baby wipe and toilet paper, and I didn’t notice any smell. I just went to the bathroom a bit ago. It’s now 8:32pm, and I noticed a strong smell coming from my vaginal area. This has never happened before, or I haven’t noticed atleast after sex. I’m just curious if something is going on? I’m trying not to google or anything, because I will freak myself out.
