Has anyones daughter had issues with this medication when starting their period?

The question to be posted. My first girl turned 11 last month, and this evening she started her period. I know everything about it been there, but she is ADHD and diagnosed with OCD. She is on medication for them, Concerta and Prozac. She goes next month for her check-up, but I would like to know now if any other mamas have had issues or effects with their daughters and medication when starting.
