Ouch. Please help

My husband and I used a regular, water based KY lube 4 days ago and today it’s burning when I pee and everything hurts down there. Am I just having a reaction to the lube this many days later??? What can I do to stop the burning 😫 and I always pee right after sex and never have had this problem before without the lube. I just don’t know why it’s happening almost 5 days later
