<s>[INST] Hello doctor, I am 26 years old. I am breastfeeding (not exclusively) my 9-month-old baby due to which I am having irregular periods almost every month. They get delayed for 10 to 15 days. Now, I am on vacation and really do not want my periods for at least 10 days to come as there will be a lot of traveling as well. How should I delay my periods without knowing the date? Which tablet should I take and how? I was thinking of Ovral G. But, will the medicines work as the date is unpredictable? [/INST] Hello. In breastfeeding, serum prolactin increases. That helps in milk production. Even for increasing breast milk production, sometimes prolactin has been given. Prolactin depresses/reduces/disturbs the menstrual cycle. Before six months of age, breastfeeding mothers better avoid hormonal intake as through breast milk can transfer to the baby and in the very early days after birth, it is difficult to digest. It is better to have weaning and early food for your baby as now he/she can have fresh juices, banana, cereals, etc. I suggest you have tablet Primolut N (Norethisterone) 10 mg twice daily from now and continue for two to three days before you want to have periods as you have irregular periods. Consult a specialist doctor, discuss with him or her and start taking the medicines with their consent. Primolut N will give you withdrawal bleed within one to two days at the maximum after stopping the medication. For more information consult an obstetrician and gynaecologist online --> </s>
