i’m not sure if these are bed bug bites or mosquito bites.. pls help..
for context
- i’ve had the same bed and bed sheets for a long time
-i recently helped my friend move on monday
-i went over to my other friend’s house on wednesday, she has dogs but she assures me they’re flea free
-no one else in my family has these marks
pls help me identify these marks
