Noticed something weird, really need advice

So I went to go take a shower, and then I had noticed these little red bumps on the areola and my nipple was red (just the nipple). From what I’ve searched up, it’s linked to early pregnancy and that worries me because I’ve never had sex, so I have no idea on what it could be. Please help. (Sorry if this is put into the wrong group, I wasn’t sure where else to put it.)
