What could it be?

About 3 days ago me and my boyfriend had sex like 6 times in a day and my labia minora felt a bit swollen and near my vagina was a bit itchy and being today, I now and then have a little bit of thick white discharge and I’ve had yeast infection before and I’m scared I have it all over again and I don’t want that to be the case, it has no odour also it isn’t as itchy when I had yeast infection last time. Any ideas what it could be?
