Taken 2 Clear Blue tests and both came back negative last night. Looked at them this morning and there is a thin blue line that’s making them both look positive. I know it was over the time but I’m now really worried that something is wrong. (Been reading about ovarian cancer/ tumours of Pituitary glad that can cause this). It’s not an evap line as there is definitely colour. How worried do I need to be? (Realistically I know I’m not pregnant. Don’t know what made me test).
