What to do if i was going into bed and i found a bug. can it be a bed bug?

Here is a photo of a: Bed bug. You normally don't see a bed bug (they are nocturnal). The adult is 1/4th inch long & flat. Here are some tell tale signs that your bites are being caused by bedbugs. First you may notice blood smears on your bedding (yes this is your blood). Remember that the blood smears usually turn black over time. Second you may see amber colored “shells” which occurs when the bed bug sheds it's.
