Letrozole

Hi , I have been on Letrozole for two months now and started off quite well side effect wise , just hot flushes, night sweats and hair shedding , but I now find I’m low in mood, have put on half a stone and am bloated like I’m 8 months pregnant ! What I want to ask please if anyone has had these side effects and do they settle in time? I’ve also had bone pain over the last few days .
