clomid?

Good morning beauties, had an appt with the Dr yesterday. After 3 mths of taking progesterone he now wants me to take clomid as well. I have to say I'm feeling abit defeated. I went 5 mths with no meds, had irregular periods but had a peak ovulation every month. Did progesterone for 3 mths had regular periods but no peak ovulation just all highs. I explained this to him, he didn't seem too concerned but wants to start me on clomid. Progesterone really increased my moodiness during pms and from what I hear clomid does the same. I'm very torn and a bit scared right now. I really hate take meds, what are your experience with clomid
