Late Ovulation

Anyone on clomid for late ovulation?! The last two cycles I've ovulated around CD 23-25. I'm currently on CD 28 and have not ovulated yet. My OBGYN recommended clomid. I am hesitant. I have had two chemical pregnancies and I'm thinking that's why she is recommending it. My husband and I are meeting with her next week to discuss further. Any recommendations of what questions I should ask when I meet with her?! Also I've read about be mucinex prior to ovulation and the pineapple core post ovulation. Any advice on that?!
