Hello Doctor,


Is it normal if my 11-year-old daughter had her first period but hasn't had her second one yet?

Thank you for reaching out to Dr. Galen. Please find the below response to your query.


Yes, it is entirely normal for your 11-year-old daughter to have her first period and not experience her second one yet. When girls begin menstruating, especially during the early stages of puberty, it's common for their menstrual cycles to be irregular. This irregularity can include variations in the timing between periods, as well as fluctuations in the flow and duration of menstruation.


During and after puberty, the body undergoes significant hormonal changes as it adjusts to the menstrual cycle. These changes can lead to irregularities in the menstrual cycle, and it may take some time for a regular pattern to establish. It's not uncommon for girls and young women to experience varying lengths of time between their periods, and in some cases, this can extend to several months.
