Clomid

Well after not being able to conceive for a year, tomorrow I have my next OBGYN appointment and my doctor has said he plans to put me on fertility meds. Clomid. How does it work? Is there a good chance I'll be pregnant in the next few months? Feels like my heart chips away every time I get that negative test. I am so in love with a child that has not come yet and my husband and I are just ready.
