Idk what to do anymore :/


So came off birth control a little over a month ago. Had a normal period the week after I stopped (when I was supposed to have my period) but now I’m a week late for my next period and all negative tests? I wasn’t very regular before. Could I still be pregnant and maybe ovulated later? I wasn’t tracking. And also was never keeping track of periods when I had my other two so I have no idea. 🤦🏻‍♀️🤦🏻‍♀️
