Missed period negative test

Amy • Wife to a good man, Mama of a 7 year old little boy & expecting our new addition April 30 2019

I missed my period yesterday still waiting to see if it comes, I took a couple cheap tests both negative BUT I did just have a wisdom tooth removed 2 days ago so I’m wondering if maybe that’s why it’s late in the first place. Has anyone else ever had this experience ? Or know someone who has ?
