Hi Doctor, I am 34 years old and have 4 years old kid. My last periods date was 23rd June. My usual cycles after my first kid have been 28 - 33 days. But this month 10 days have passed and I still did not get the periods. Home test kit shows negative result. Can you please suggest what may be wrong and what should be done? This is the first time my cycle has been delayed this much. I am worried since we want to go for a second child. Please help.
