How oodles times are you allowed to nick plan B Pill?

I was wondering if here is a limit to filch the the plan B pill. A friend of mine has taken it 3 times or Twice im not sure but she desires to again and we heard that if you took it 3 times you would not be capable of have children. Is this true ? nearby is no case of overdose on plan b...but its really risky to help yourself to...she's probably gonna feel crappy and wet retention.also...shes gonna grow hair..
why doesnt she progress on birth control.
plan b is bc...just within heavier amounts.
No, there is no constrain. But if your friend is needing it relatively often after she should be on birth control - it's easier on the body and much much cheaper!
