Can you help me determine if this is normal for my daughter who is 13. Her periods started about 9 months ago and are still very irregular, I understand it's normal and they can take a while to settle. They show no sign of settling yet, she's just gone 3 months without a period. They are so heavy, she bleeds through even the thicker night time pads within an hour or two. She just sat on the sofa briefly and bled all over it, ruined her bedding last night, despite getting up in the night. She's in agony and taking pain killers, plus she's vomiting. She's quite shy and has said she doesn't want to see the GP, I think she should. Is this normal in the early months? Thank you.
