<s>[INST] Hello doctor, I am a 25 year old female, and I am trying to conceive for the last 1.5 years. My husband works for a month in another country and has 15 days of leave. So, when he goes to work, I do not accompany him. We have tried conceiving many times, but we did not have any luck. My menstrual cycle is regular, and it is of 28 days. I also got a Humog injection last month, but it did not help. Can you please explain in which days should we try to conceive? Thank you. [/INST] Hi. How are you doing? Let me start on a positive note that, you are at the right age for pregnancy (19 to 35 years), so never lose hope. Hope I have cleared your query, do write back. All the best.
