Call your local clinic for advice. If you choose to handle this alone, I suggest flushing as many other people have posted above. Or you can simply apply heat. Bedbugs have a very low tolerance for heat. 120F for a few minutes causes them to migrate, longer than that, they die. Place a heat source near your ear. Near your ear, about six inches, not on it. A heat lamp, if you have one, or a flood light will do in a pinch. It should come out on it’s own.
Next you must deal with the infestation. If this came from your home, a chemical fumigation service is probably the best solution, but a lot of people don’t tolerate the poisons used, although the services claim they are safe.
Otherwise, you can do it old school. Bedbugs like to live in dark, cool places, such as deep in the stuffing in bedding and sofas. You can close up your home and max out all it’s heat sources for a day to raise the inside temp over 100F for 24 hours. Or you can do as they did before central heating: place all your bedding, pillows, rugs, and upholstered furniture outside in the sun for as long as possible on an 80F+ day. They will migrate somewhere else. As it is the middle of September, you might not have many 80F days left before winter sets in. All your clothes, especially coats and jackets, should be run through a dryer on high heat for at least 30 minutes.
Good luck.
