If nobody ever taught you about periods and now you have a daughter who is getting hers, you are not alone. Most dads were never given this information. Here is everything you actually need to know, in plain language, without awkwardness.
What is going on?
A period is the monthly shedding of the uterine lining, which happens when a girl is not pregnant. It typically lasts 3 to 7 days and occurs every 21 to 35 days, though cycles are often irregular in the early years. Girls usually get their first period between ages 10 and 15. Periods are accompanied by cramps, mood changes, fatigue, bloating and sometimes headaches. These are all normal. Knowing this means you can respond practically and calmly when she needs you, rather than feeling helpless or uncomfortable.
What is normal:
Key takeaways
- Irregular cycles in the first one to two years after the first period
- Cramps that range from mild to quite painful
- Mood changes in the days before her period, often referred to as PMS
- Heavier flow on some days and lighter on others
- Fatigue, bloating and breast tenderness around her period
- Her cycle settling into a more predictable pattern over time
What is not normal (seek support):
- Period pain so severe it regularly prevents her from going to school
- Periods lasting longer than 7 days consistently
- Bleeding so heavy she is soaking through products very quickly
- Complete absence of periods after age 15 or 16
- Significant mental health impact around her cycle
Your teen’s perspective:
It was a bit strange when my dad asked if I needed anything. But it was also really kind. I did not need him to know everything. I just needed him to not make it weird. The fact that he could say the word period without cringing made it so much easier for me.
How to start the conversation:
- “If you ever need anything when your period comes, just tell me. No big deal.”
- “I want you to know I am comfortable with this. You do not have to hide it from me.”
- “Is there anything you need at the shops? Pads, paracetamol, anything?”
- “Are you okay? I know this time of month can be hard sometimes.”
Do:
- Know where the period products are in your house
- Be willing to buy period products without making a production of it
- Take her pain seriously if she says she is cramping
- Ask if she needs anything practical without going overboard
- Use the word period normally and without discomfort
- Download The Ladybird Club app for her so she has her own tracking tool
Avoid:
- Treating periods as something she should hide or not mention
- Making her feel embarrassed for bringing it up
- Dismissing her pain as normal without acknowledging it
- Referring to it only by euphemisms as though the word itself is shameful
- Leaving all period-related things entirely to her mother
Watch for:
If she seems to be in significant pain regularly, is missing school because of period symptoms or seems distressed beyond normal cycle changes, speak to your GP. Conditions like endometriosis are common and often dismissed. Be her advocate.
When to seek help:
Worth knowing
Severe period pain is not something to just push through. If her cramps are consistently very painful or significantly affecting her quality of life, a GP visit is worthwhile. There are effective treatments available.
In the app:
The Ladybird Club gives your daughter a private space to track her cycle, understand her hormones and learn about her body. As a parent on the paid plan, you can see her cycle phase without accessing any private data, so you always know when she might need a bit more support.
