Yeast infection/UTI

So I just got our first faint positive on Friday then was swimming this weekend. Today I think I definitely have a yeast infection and possibly even a UTI. I haven’t called the midwife yet to confirm pregnancy. But hubby just got a clearblue digital and it says pregnant. When I call the midwife tomorrow do I need to tell them I mommy concerns or can I just buy the over the counter stuff??
