I Need Help ‼️

I'm 16 and of course I'm a female. But I heard that boys have little bubbles inside their pee after sex. Last night me and my boyfriend had sex, we wore a condom and when I got up to go pee I had little bubbles, this morning I got up to go pee and I just a small amount of bubbles. I looked it up and they said it's not a sign of pregnancy or anything. But I'm still kinda worried. My period isn't until 4 days. Does anyone know what the bubbles in my pee mean.
