9 dpo period?

Werdah

Hey ladies. I ovulated cycle day 21 and now on cycle day 30 (9 dpo) I started my period. I'm never late for ovulation and never early for my period. That was such a short luteal phase. Is something wrong? I did a pregnancy blood work yesterday at 8 dpo (routine) and came back negative. I confirmed ovulation though ultrasound. I also had an SHG done but at CD 13. I'm hella confused.
