Questions:

So Iost count of how long we've been trying to concieve but to me it feels like it's been long time haha but anyways I was just wondering what doctor should I speak with if I'm having problems or concerns about concieving and things like that I'm really worried that I won't be able to concieve & I just want to do all the tests to make sure I'm in good health & able to concieve ! should I make an appointment w/ an obgyn or who should I speak with to get these tests done & talk to ? Thanks
