Red, Itchy Bites on body?

[brookerspink]

I've been getting some type of red,itchy bites on my neck, shoulders, stomach, waste etc. I've once gotten bite on my head and it felt like a goose egg. Im not too sure if its bed bugs because theyre are no signs of them. The biteing has gone on for about a month now and still hasnt stopped. I was wondering what it might be?
they bites are simular to misquito bites and they only happen at night
