I had uniary infection and they gave me a medicine and it got better. I don't have the infection anymore. I was supposed to have my period and it did not come. It's been two days. My period is always on time. It's never late or early. Can I be pregnant? We tried before the infection! It is possible my period didn't come because of my infection? What's the reason behind it? Did anyone have the same problem? I'm not on birth control.
