It is difficult to be sure about this. Everybody is different in how they react to their blood being extracted from them by a bedbug, which usually happens to you when you are asleep in your bed at night. Most people do not get this effect, But if you are getting black marks this is most likely to be part of the allergic reaction specific to yourself caused by the bedbug injecting the coagulant and anaesthetic into your bloodstream for its self protection when it first crawls on to you, and before commencing its meal of your blood.
Everybody is different. With some people there is no perceptible reaction and they often do not even know they have been bitten, some get just very small red bite marks, some just extremely irritating itching which makes them scratch frantically to get relief and some get horrible looking big red blisters on their skin, which with some people do not appear for many days after the bedbug's visit to them . One other possibility is it may be a result of you scratching where the part of you where the bedbug inserted its sucking tube into you after the anaesthetic effect had worn off, and if your finger nails were dirty when you scratched yourself perhaps while still fast asleep.
Bite marks can be used in solving crimes by comparing the patterns and characteristics of the bite marks left on a victim with the dental impressions of potential suspects. Forensic odontologists analyze the size, shape, and alignment of teeth to identify the individual who made the bite mark. Additionally, bite mark analysis can help provide evidence to establish a link between the suspect and the crime scene, potentially leading to their identification or exculpation.
I would assume that as with roaches or any other similar types of bugs, that there is almost certainly more than one bedbug in your apartment or house. I would call an exterminator or bedbug specialist immediately.
