Weird matchmaking in small regions

Recently I have been queuing a lot as a trio on ranked, today I wanted to play some ranked alone. I am gold 3 rn almost plat. I queued up and got nothing but plat 2+ on my team and the enemy team. Also my last game had 3 diamonds. Is this normal in small regions or my mmr is weird?
