So, after 2.5 years of trying and never once having any kind of spotting.....It's been 7 day since we did an at home insemination and I found some spotting.  I am not certain if its implantation bleeding but I'm certain it's blood and I never spot. Ever. I don't have any conditions that might bleed to spotting. My periods are super regular.  PLEASE SEND BABY DUST!  My wife and I are so ready for another baby and our daughter will be an amazing big sister :)
