Lost!!

I am 70 days late. Not pregnant. And my blood work came back pretty normal that I am now on the bottom of the priority list to figute out what is going on. I am confused and sad and frusterated that I dont know what is going on with my body. Was looking for encouragement or advice or anything to help from you guys. Has anyone experienced this? Is there anything I can do until I get to see a Doctor? I came off birth control the beginning of May. Had normal periods until July 10th and have not had a period since. Any chance that my body is still adjusting? Helpp please 🙈
