I've been doing ovulation tests since CD9, which I know sounds early but I'm pretty sure I ovulated early when I fell pregnant with my son. The last two tests, there was something there for sure, two pink lines but the test was never stronger than the control line. Today (CD12) and nothing. I mean there is the hint of a line there but nothing compared to the last two tests. Has anyone ever had anything like this happen? Is this common? I don't really use OPK tests so I guess I'm still pretty novice to their weird and wonderful ways! I have however, made sure I test at the same time each day. Any advice would be greatly appreciated.
