<ul><li>Sometimes, when you’re having a particularly heavy flow day, it can feel as if something is wrong. Surely it’s not normal to produce this much blood?!</li><li>Although it may seem like a lot, your body only actually loses around three tablespoons of blood during your period; the average woman can lose anywhere from one tablespoon to a small cup of blood during a normal period.</li><li>If it seems like you’re losing more than this during your period, you should seek advice from a medical professional.</li><li> Losing too much blood can increase your risk of anemia — which can cause dizziness, tired and poor circulation.</li></ul>

<ul><li>Back in the 1800s, girls wouldn’t get their periods until they were well into their teens — the average age was around 17.
