Hi, we've been trying for a baby for over a year unsuccessfully, and this month after our baby making duties nearly 9 days after ovulating my wife keeps saying she feels like she's going to come on her period which isn't due till a week today, she said she caught her boob the other day and it was a bit sore and tender, also she has this weird feeling in her chest in the centre like she can't take a deep breath and when she does she gets a bit of discomfort, am I just clutching at straws? Or do I actually have a case to feel that this time could be the one?
