Hormone birth control pills are very effective ( 99%) in preventing pregnancy
. Taking the Oralcon
tablet 2 hours late is not going to reduce its efficacy. So don't worry about that matter.
It is important that you understand that smoking in addition to causing harmful effects on health also decreases the efficacy of oral contraceptive pills
. So you should cut down on smoking.
I also advise you to use barrier method of contraception
like condom regularly to protect yourself from STDs.
