Nervous about starting Clomid

[MamaBee2Glory]

After losing a baby at 13 weeks in April, my OB/GYN did a ton of tests and found out that I have an adrenal gland disorder.  It seems I'm not ovulating. My Doctor is going to start me on Clomid my next cycle.  At first I was happy that they found something that would explain why it takes so long to get pregnant.  Now that my period is due the end of this month and I have less than a week for this new process to start I'm nervous.  I can't really explain why.  I have wanted a large family for some time, but my soon to be 4 year old daughter is all I have to show for years of trying.  I'm unsure of what to expect or how long this could take.  I think I may cry over it.
