This vaginal spotting could may well be implantation bleeding, although of you missed your period two weeks ago it may not be, my best advice would be to take a pregnancy test and better yet visit your doctor for a blood test to be sure. i am sorry to hear about your miscarages and i really hope this is the month for you! sending you lots of baby dust x
I had that when I was pregnant....def go see the doc just to be sure!
