Thyroid?

Normally when I take a new dose of my levothyroxine my period would be off track and come a later day. Well this past Monday I started a new dose . I was also to start my period Sunday before or that Monday . Never came , I’m 5 days late.... could it be the medicine-or maybe pregnant! ? We have been trying! 🤞🏻🤞🏻🤞🏻🤞🏻🤞🏻I’m going to test in the morning. Was curious of your thoughts..
