In brief: Bed bug bites may

Cause no sx's/signs in some except for 2 small points where skin was punctured.
When there's a reaction, it may show as fast as an hour or may not show for several days after being bitten. It can cause itchy, pink, swollen, lesions with a clear center. In cases of hypersensitivity blisters may develop. A telltale sign is linear track from sequential feedings – but doesn't always happen.

Bites are usually in areas that are exposed while sleeping-arms, shoulders,neck & legs. Your dermatologist can definitively diagnose.
