Allison, we suggest you to see a doctor for a diagnostic, just in case of, because nobody before and after you complained about bites since 1 year we bought this matress. Other girl is here since 10 days, and she has nothing. Us as well we already slept in this bed, and nothing...You stayed 4 nights here and 1 day after leaving you let Luis know that you had bites, why so late?... Furthermore, you could have let us know that you found a cockroach in the bathroom, and we would have put product. We leave in a humid country and it can happen that a bug enter in a house. You just had to let us know.
