Right, I need a talking to.
I'm 7dpo and obvs got a bfn this morning because of course I bloody would. 
But because Iman obsessive freak I just used a one step opk. When back to it after about 15 mins and it's a faint positive but was definitely a strong positive on the day it should have been.
I dont really know what I'm doing with opk's but could it mean something? Or do I need to get a grip? Be honest, I can take it.
