what is this ?

Ok so I woke up with these dark splotches on my upper lip . They weren't there yesterday and no it's not a hickey or a bruise from kissing I haven't seen my bf in a few days. It doesn't hurt. my mother thinks It could be " chloasma " I looked into it and it's supposedly refered to as the "mask of pregnancy ". But idk if it might be too early for that to be what it is because I'm 11dpo . Any ideas?
