Do i need to takes birth control pill, minastron, if i took plan b because i forgot to take minastrin this morning?

Yes: If you forget your birth control pill, you should take it as soon as you remember it. However, if you don't remember to take it until time for the next one, you should not take two at once. You should just take the one and consider the missed one skipped. The trick to birth control is that it HAS TO BE taken at the same time every day. If not, you risk breakthrough bleeding and pregnancy.
