Here is my story I am 31 DH is 30 we have been trying to conceive for 2 years now. This month I started charting for the first time. I took a test at 10 dpo and got a faint but clear positive line. Took another at 11 dpo and it was neg. Took 2 more at 12 dpo and it was a faint but clear line again went to the doctor for a blood test that came back Negative so figured I was out. then at 14 dpo took my last test and it was a faint clear positive again. But this is why Im confused im about 18 dpo now and today my test was negative I took 2 both negative.. So please if anyone has been through this let me know your story im so upset.. Thanks
