New clomid user with questions

Jazz

Good afternoon girls, I just wanted some advice to clear my head. I do have an appt with my dr tomorrow.

So I started clomid on cycle day 3 ( first round) on my fertile days I started my period . I know this isn’t normal, That’d make my cycle 17 days , do you guys know what might be the cause? Exactly a week ago I had the most intense pain on my ovary . I’m just looking for advice I guess waiting for the dr keeps me anxious 😢
