Ttc appointment help!

Hello everyone. I have an appointment Wednesday for my Ttc struggles I am 22 with a 4 year old daughter and have been Ttc for over a year. This has been such a stressful struggle. I had a chemical pregnancy about six months ago. Other than that, nothing. I am having a hard time with my child wanting/needing a sibling so bad and me not being able to have another. My doctor mentioned my last appointment about starting me on clomid. I was Wondering if anyone could give me any advice or input of questions I should ask at my appointment. Thank you so much!
