I'm thinking I probably got a UTI so I'll go to the doctor on Monday. Until then what should I do about the symptoms and to make it not get any worse? I have some antibiotics here but every time I take them they make me throw up and feel sick so I refuse to take them again. And I dunno why I'm so prone to them this year, I thought I was careful but I guess not. It's really frustrating to me. And once I get antibiotics I know it lowers the effectiveness of BC so I guess if I want to have sex I use a condom ( which I always do) and I'll make him pull out since I'm so paranoid. Or should I just abstain from it until, if I have a UTI, it's gone? After I take my antibiotics how long do I have to wait until my BC is fully effective?
