3 days till AF

rosie • Hi, I`m 26 and a mummy to my gorgeous 9 year old twins. I`ve been with my current partner since Jan 2014 and we`ve been ttc for over 6months.
Me and my OH have been trying for over 6 months, This time round its been different. At about 7 dpo i suspected i was having implantation pains ( sharp sudden tugging on the right side of my uterus). At 8dpo my boobs began to feel different so i did a cheap test and got a vvfaint line. And this is all i keep getting. Yesterday 10 dpo i took two cheap tests both showing lines but one noticably darker. Still have tender boobs and feel achey. This morning we decided to try a clear blue and i got a BFN but on closer inspection it showed two lines still 😕 . Can anyone see what i'm seeing? Please ...
