DD1 is toilet trained but loads of accidents today....help!

[BlameItOnTheBoogie]

DD1 who is 2.9 has been doing all her pees in the potty for 7 weeks. We only cracked poos last week but she has been totally clean and dry since. Today started off well but after a normal morning she's wet herself 7 times! She's knackered after a late night travelling last night and has a bit of a cold. Would this make a difference? Is this just part of the process?
We've run out of bottom halves!

My dd's have both done this when unwell with a cold. They also had UTI's to so might be worth having it checked out?

Thank you. That's good advice. She's been complaining of a sore bottom. It's a bit red so I've been relying on Sudocrem but maybe it's more of an internal pain. I'll see how she does tomorrow.

my dd has accidents when unwell and when teething.
