Missing the last pill of your pack

Nat

I’m on my second till last day of my pill pack and I noticed today that tomorrow’s pill the last before my break is missing. I haven’t taken it it’s missing. I don’t have a spare pack Because I was going to re stock during my break. My clinic isn’t open tomorrow because it’s a Sunday and I don’t know what to do

What will happen if I miss this pill

I take Gedarel® 30/150
