Bed bugs?

Background: went with gf to Prague before Christmas, went home for Christmas, came back to apartment last week. GF complains about itching skin, doesn’t think about it any more. Next day has 4 bite looking wounds (like stung with needle or something) and find a bug in bed (did not look like bed bug, not that round). Called the exterminator that couldn’t find anything, but did say it could potentially be at an early stage.

Then last night I discovered these two small red stains, do I perhaps have bed bugs after all?
