Helllppppp meeeeee

Victoria • Harley's mommy 💙👶🏻12-4-16 Due with baby #2 Oct 2024 👶🏻
Does anyone know wtf this is?! I'm 20 years old, 21 weeks pregnant (don't know if it has anything to do with it) and this thing just appeared out of nowhere! It doesn't hurt, itch or anything. It just feels dry kinda scabby and it's a TINY bit raised. There's no hole like if I got bit by anything, haven't gotten burned or scratched. 
And I'm a total Google Hypocrondriact so I'm convinced it's skin cancer...lol 
Plz help
