Hi, my wife is 30 years old and gets periods regularly within 26 to 30 days. We have a child two & half years old. Now we do not want her pregnancy for another two years. Presently we use a condom as a contraceptive measure .( excluding safe days) . But sometimes when her period gets delayed , we become tense, doubting that our judgement of safe days might have become wrong. So to avoid such instances, kindly suggest the safe and secure, long term contraceptive method. Also now also her periods are delayed, so please suggest any pill to pre pone her periods .
