Started period 7dpo....

Started light spotting yesterday and period this morning. I ovulated on the 26th-27th (cycle day 27 and 28) and started my period 7 days later(today). I used digital ovulation tests so I am positive I ovulated at that time. Should be worried that I ovulated so late in my cycle and started my period so soon after ovulation? I haven't had much cramping at all and I usually have really had cramping. My cycles have been long the past 5 months TTC. This will be my 6th cycle TTC...
