May have accidentally taken thyroid medication twice?

I am almost 30 weeks pregnant and on a very low dose of levothroxine, 50mcg, there is a possibility I took my pill twice this morning but I don’t know for certain. My daughter has been up with a fever and throwing up since 230am so I am exhausted and honestly can’t remember. Should I be worried? I know that it’s a slow acting medicine and most of what I read said once is no big deal but I just wanted other opinions. Both my OB and Endo are closed this weekend so I don’t really want to call the after hours number if it’s not necessary.
