Clomid question

Saundra
Hey ladies! 
I have a question about clomid. I started my second round 100mg at the beginning of the month, on cycle day 3 I believe. Took it like normal. All of a sudden last week I woke up and had started a full on new cycle. I called the doc and she said she's never heard of it happening before. I  got 2 periods in less than a month!? Wth? She said this month is a wash. Has this happened to any clomid users before? Did anyone get a reason behind it or still end up successful in getting pregnant? I'm so frustrated.
