I’m freaking out !!

I’m almost 5 months postpartum and had my tubes tied during delivery. My husband and I had sex on November 13, and according to my tracking app, I ovulated on the 16th. I am supposed to get my period 2 days ago but still no period 😫😫😫. I’ve heard stories where people still got pregnant even after they got their tubes tied. Now I am freaking out!!! I hope I get my period tomorrow or I will have to take a test 😫😫🙏🙏🙏
