Anyone able to say if they've experienced this PLEASE. TTC for 15 months now. Every month same sympton spotting behaviour. Two things different this month. CM that was possible implantation and this weird on/off pain in my right breast. The only way I can describe it is that it's like an electric shock on the inside or sharp growing pain. I was wonder has anyone ever experienced this? I never had this in my first pregnancy 8 years ago so it might not be pregnancy related. But
