Baby slept in my bed when ill now hard to go back to hers

My 22 month old has never been the best of sleepers but has been good at sleeping in her own room. However, for the past week I've suspected she's been having her bottom molars coming in (dribbley, prone to upset quickly, bad sleep). One night she just wouldn't go down and it was 1am and I just gave in and let her sleep in my bed (she didn't for 3 hours but then finally conked). Then a couple nights later she was waking again and I was also knackered and plonked her in my bed. Now she's started asking for "mummy bed" a lot. She's developed a hacking cough, pos related to teething that's woken her up early on in her sleep tonight. I just couldn't get her to go down and was going to relent and just put her in my bed but I'm worried we're in a bad cycle now and whenever I put her to bed that's all she wants. My partner intervened and she went hysterical but he managed to calm her and for now she's back asleep in her own bed. What do people think? Should I be persisting more or if she's still poorly is it OK and when she's better she'll get back into her normal sleeping habits? We've worked so hard to get her to sleep happily in her room and I don't want to ruin it! Ps we don't do cry it out, we only ever do a much softer and shorter ladder version and never leave her more than 2 mins of crying. No judgements please re any kind of sleep training, am frazzled and not here for that kind of input or criticism!
