I've just come on my period, 4 days late, and for the first time ever, my period blood smells absolutely horrible. The colour has turned from light red-ish to a darker browney-red and it is more clumpy and leaky. I've looked up on the internet to see what may be the problem and all I've seen people say is this usually happens at a older age, when you've had children, or if you've left a tampon up there and its lost or something. I've never used a tampon, I've used pads since I first started and I've just never bothered with tampons. I'm only 19, I've never been pregnant and I started my period when I was roughly 13. Is this normal?
