8 months mature, darkness terror or teething?

My duaghter just turned 8 months old + for the past week she have been very stressful during the night + her nap. She constantly wakes up crying + last night be the worst, she woke up at 12:57am then i brought her into our bed, she fell asleep + then woke again screaming with tears at 1 afterwards again at 1.45am. I am soo tired + its just happened all of a sudden. Do you deliberate its night terrors or teething? she was partially awake when i went to get her but i'm not sure.. we are all losing sleep + i am really worried more or less her. What could this be?
anything i can do?

any advice thanks x
