I broke my lady bits! ๐Ÿ™ˆ

Ok, so I totally messed up!ย 
I had a moment thisafternoon where I thought it would be a good idea to tidy up my lady bits in preparation for labour at 38 weeks! BAD IDEA!ย 
I used veet sensitive and managed to get a tiny bit 'inside' holy hell, does that hurt!
Then to make matters worse, by hubby came home early and decided it would be the perfect time to have some 'afternoon delight'
Now I can barely walk as it feels like I have set a bagel on fire and stuck it between my legs!!! I tried applying nappy cream....nope!!!!! Burn!ย 
Any ideas on how to treat it? (Id rather not put 'food items' e.g. Yoghurt down there)
