Which sentence is grammatically correct?
"I've been really busy these days"
"I'm really busy these days"
I may be wrong but for some reason it feels funny to use "these days" with the present perfect tense since, to me, "I've been really busy" implies that "I'm not that busy anymore", which is in contrast with what the phrase "these days" implies (= "I'm still busy"). Am I wrong?
P.S. I have asked this question to some native speakers of English and I got some contradictory answers. Could it be a regional thing?
