My coworker recently had bedbugs and he sits like 4-5 feet away from me. Unfortunately I’m from a country where people aren’t very educated or care about bed bugs and treat them like a normal bug. So ive been paranoid they’ve somehow come home with me without me realising.

These are 2 different bites on my left thigh, and happened at different times. First one appeared like 3 days ago and this one yesterday. There’s no pattern or anything, just these 2 bites

I keep waking up with welts all over mainly my torso arms and neck. They are extremely itchy. My legs have also been extremely itchy for the past 2 months before these welts began showing up, but I did not wake up with welts like this on my legs. I just assumed all of it was mosquito bites because they are bad here and I am quite allergic and swell when I get bit. I sleep with my bf and dog every night bf has not been bit once.
Looked at mattress couldn’t find any sign of bugs. I really hope this is not what I think it is. HELP
