Okay, so this is hard to explain.. I've been trying for 4 years. I finally came to the exception that I don't think I'm able to have kids. But, I've been drinking like crazy, smoking like crazy and not giving a flying f. Am I wrong to do so even though I think there's a huge possibility that I may be pregnant? Honestly, the concept of me being pregnant could not even be a thing, but should I worry?
