Marie • Have Pey 9/08, 1 angel baby 2011,and TTC again
Ladies I've been having some signs of pregnancy but they are also common with a period. Today I felt weird like I was starting, I just went to the bathroom and had a ton of mucus with pink blood. I'm on day 28 out of 30. I've NEVER had mucus during my period... Could this be late implantation ????? Picture below
