Hi, I don't even know if I have posted this in the right area of mumsnet, but hopefully someone can help or point me in the right direction. My dd started her periods last August just weeks after her 14 birthday and has had them regularly up till 31 jan 2012, the start of her last one. Nothing since. She is very open about things and has not seemed worried or anxious by this and she knows the facts of life better than myself, so if there was a chance of being pregnant she would be concerned. I will however do a pregnancy test in a secret way by asking her for a sample to take to doc to rule out kidney infection, and then dip a pregnancy stick in it to check. My dd is very small for her age, height wise, perfectly proportioned though, and no learning difficulties etc. she has been a bit stressed by GCSE work and assessments, but I can remember being much more stressed and my periods were never affected. Does anyone have any experience or advice as my mind is running away with me about pituitary tumours and all sorts. Please, please help. I need to switch off as she has just come down with a bit of a headache and I need to go to her. Thank you.
