Late, but negative test?!

My period is now nine days late and I’ve taken two pregnancy test and both were negative. Me and my partner did have unprotected sex (pull out method was used) when I was supposedly ovulating. (Usually I can tell when I’m ovulating because I get slight cramping but I didn’t get it this month, so maybe I just didn’t ovulate?) We just moved and I realize it could be stress from that and figuring out life lol but it’s never been this late before. I really don’t feel “pregnant” either I’m not sick and my breasts aren’t sensitive. (May I add my grandmother didn’t realize she was pregnant until she was already four months because she had no symptoms) We wouldn’t be mad if I was pregnant! Just want some advice or to hear from others who have been through this! Thanks! 😊
