[ee-chee]

💬 Usage Tip: [1か月後] means “one month later/after one month.” In medical follow-ups, it often means “come back in one month” for monitoring. Fun breakdown: [後] means “after/later,” and in time expressions it often follows the period, like [1週間後] = “one week later.”

🇯🇵 In Japan: At Japanese clinics, doctors often give very short follow-up timing like [1か月後] or [2週間後]. If you are unsure whether it means your next visit, your test, or when results will be checked, it is completely okay to ask politely: [1か月後に来院ですか。]
