Good sleep hours and fixing hours please help

My 3 month old recently messed up her sleep schedule and last night we had to completely stop swaddling her and got her some sleep sacks she slept really well only woke up a couple times to babble to herself and fell asleep perfectly fine she went to bed around 7pm because she was falling asleep and wanting nothing to do with anyone I woke her up about 11AM because she wasn't awake and I was getting really worried about her because I couldn't see her face in the camera as she somehow pushed herself towed the head of her bed how do you guys deal with the no swaddling life how do I know when to wake her up or how many hours is to much
