Plan B

How many have taken the plan B and did you have any side effects or reaction to it?

Husband and I had a scare last night. I have 5 kids (one who was just diagnosed with an autoimmune disease). We can’t have another baby right now as much as I would love to.

Also my understanding when I read about it is it’s not an abortion pill it’s just another form of a birth control. Is this true?
