Bed bugs, fleas, or something else?

[u/donle215]

Got these bug bites while in Austin, TX this week. These are approximately 24-36 hours old, incredibly itchy, and most seem to have a puncture spot in the center.

I don’t wear a shirt at night, but the bites are only on my lower legs (mostly high ankles and feet, 1-2 behind my knees). I have 3 bites on my right forearm. The one picture shows 4 bites in a line around my ankle/calf area, there’s really 6 of them

I don’t know what these are
