Back molars

Anyone's baby cutting through back molars? I can see one about to pop out and boy it's been weeks of shit sleep - crying in sleep, constantly on and off boob.... I do teething powder, anbesol, amber bracelet, gave Calpol last night..... Just seems to not work, only boob and sleeping on me does, which I wouldn't mind, but she wants to sleep in her cot, rolls away and wakes 😭 Any tips? None of her other teeth were bad, so I feel lost...
