feel like i have to pee all the time but sometimes nothing comes out. I've been drinking a lot of cranberry juice incase its a uti but the feeling hasn't gone away, been about a week now. ugghhh i guess I'll try to test in the morning and see what I get just cuz it's bugging me. probably going to be negative but I guess we will see.
