Are these bed bug bites, mosquito bites or flea bites?

So a strange aliment is causing me grief – (yet again)
I’ve been waking up in the night to a very mild inflamed lump on random places on my body, sometimes the soles of my feet, last night my lower back, the other night my upper back, I have this red inflamed ‘bite’ that never itches for longer than 5 mins and then I fall back asleep in the morning it feels puffy then by the afternoon it’s gone.

This happens most nights, only one singular bite.
I covered my whole body under the blankets after this episode last night thinking that if it were a mosquito it would bite the only exposed parts which were my fingers but I never got another bite.

I’m going crazy!!

We also have mosquito netting on the windows and I never hear that annoying buzz of a mosquito.

Yesterday I felt pricks and itched my leg to find 5 small little spots, I was at a park so assumed them mosquitos, but I was wearing tights and a flowing dress that has thick material so can’t have been a mosquito.

I’d love to find bed bugs right now just so I knew what it was!

My daughter isn’t getting bitten and neither is my husband just me!
We have an indoor cat but she is not itching or anything to assume fleas.

Any thoughts on this invisible bug!?

Oh I should add, I can always feel something crawling on me, but when I look there’s never anything there.
