BC and Pregnancy help

Soooo last week (Thursday 19th) I was super sick and thought I had the flu. I ran a fever Friday night and then Saturday I had bad symptoms like a UTI. Ive been crazy nauseous and I’ve not wanted to eat anything. I went to a walk in clinic and ive been on antibiotics for a uti but they didn’t actually test my urine (because I don’t have insurance and it cost me to have it tested) they gave me antibiotics based on the assumption that I did have a uti. Now my breasts are extremely sensitive. I’ve been on BC for about 1 and 1/2 months. But I looked it up and I have a lot of symptoms of early pregnancy... I’m supposed to start my period in 1 week but how long should I wait to take a test..?
