Birth control to regulate period?

Kyra • Happily married to my best friend, mother of an amazing little boy. I am a dental assistant and I love what I do!
 Hubby and I are TTC baby #2. My periods have been all messed up since stopping depo in November. I only had 1 dosage in August. My doctor has prescribed me to take Sprintec for 30 days and believes that will get my cycle to normal. Any one have anything to say about that? Thank you.
