Ovulated but no period

I ovulated on the 7th (pos opk) and my period is a week late so I would be 19dpo. I’ve obviously been testing and nothing but negatives so I’m not sure what’s going on. I haven’t had any life style changes and my periods have always been like clockwork. My nipples are super sensitive and I’ve had the worst gas. Is there still a chance or do i keep waiting for af?
