Advice..

Hey everyone, haven't post in a while hope you're all doing well. I was just wondering if I could get some friendly advice on something. So, I was thinking about making a doctors appointment and asking my doctor if I could get checked out to see why I haven't been able to concieve. However, I don't want him or her to judge the fact that I'm 18. Do you think they would? Also, is there any recommendations on how to concieve faster? Fiance and I have tried with preseed and still haven't got a positive. Thinking about trying it again .. My fiance and I talked this over at least 30 times and both know that this is what we want for our next chapter in life together. Please positive advice... Thanks!
