ovulation days after AF ended...

so weirdly i had my ovulation pains (i can feel when my ovaries are releasing eggs) on my last day of AF (10/27) i had sex that night and the following 2 days... today i’m on CD 17 and i am having the weirdest pulling sensations on both sides of ovaries... this started on saturday but was very mild... i did have sex 4 times within sunday night to this morning... so i’m not sure what is going on, my cycles are between 27-30 days averaging. could i have ovulated maybe a few days after my period ended?
