I was just wondering if a bladder infection can make you miss a period? Or does this sound like a bladder infection. My lower back hurts, and my left side, and lower stomach area hurts a little. It goes away though. My breasts are tender too. My stomach is really bloated, and it looks like it too. My pee looks a little darker, but it could just be wondering/worrying.. Sometimes even after I pee it still feels like I need to go. My period is 10 days late. :/ can this cause it?
