Idk I need help

I feel like my Areola ‘s are only dark at night or in certain light ....

I did get my period and I’ve taken hot I would be 8 weeks if I didn’t get my last period I took 2 both were negative

I’m a virgin but I did some naked rubbing no vaginal contact he never came and I’m scared that pre cum might have leaked from the butt rubbing and I didn’t notice it ? Although the rubbing only happened for like 2 minutes and afterward there was I lit a handjob I think I would have noticed the pre cum and if I didmtI don’t think there would be enough to actually leak because I check myself afterwards so I’m confused why ?
