I wonder if someone can advise me: I am really worried... I am on day 21 of my cycle, so there is no way that this is related to ovulation. Today I noticed very thin streaks of blood in my cervical mucus. I last had a smear in September 2012. I am really worried about what this blood could be. As a single mother of two I am anxious about my health anyway... If anyone can advise me I'd be so grateful. I will see the GP next week, but it is very difficult getting an appointment at my surgery. Thank you in advance!
