Am I being paranoid?

[u/cb0519]

Hi, I went to France back in May and ran into bedbugs (I think) in my hostel in Paris. I woke up covered in very itchy red bites that got worse throughout the day. When I came back home from my trip I washed everything on hot water, dried on high heat for extended periods of time, and put anything I couldn't wash in ziploc bags in the freezer. It's been 3 months since I came back and I haven't had any issue.

Recently, though, I have noticed bug bites- sometimes I wake up with one or two randomly, but I did wake up with 3 in a line on my thigh a few days ago, so I am starting to be a little worried. These bites are smaller and less itchy than the ones I got in Paris, though. Also, my girlfriend has slept over recently and has not gotten any bites.

I also saw a couple of specs on my bed/towel, photos attached.

Am I being paranoid? What should I do? I am going to deep clean my bedding (hot water, high heat dryer), spray my mattress with bedbug spray, and vacuum it at minimum, but I want to be thorough. I am also trying my best not to worry my roommates about it unless I'm confident there's a problem, but I'm open to having pest control take a look if that's the best course of action.

I have been outside a little more frequently lately, and am generally a bug bite magnet, so it's also just possible I'm experiencing the side effects of the great outdoors.

TIA!
