In brief: See below

Most insect which draw a blood meal though a bite will cause a local reaction with redness, swelling, warmth and itch.
It is often impossible to tell these apart, but bedbugs will often leave a straight line or repeat bites whereas other bugs like mosquitos, fleas, etc. May look scattered. They may look very similar at 5 days but the inflammation should be decreasing.
