Help please! Bites on thigh??

Jessica
OK so this image is of my thigh. I noticed these bites today, does anyone know if its bed bugs? I have no pets so i doubt flees, it barley itches unless i touch it and i don't wear loose clothing so i doubt midgies. What is it?? I've changed all my bed sheets and put them in an extra long hot wash as well as hoovering my bed but the thought of bugs on me is seriously freaking me out 😂😂😭
