Hi everyone, I am new to this board, but I thought I could get some advice here. Every month I spot brown blood 3 or 4 days before I get my period, well this month I haven't. My period was due yesterday and I haven't gotten it yet. Today I had some light pink when I wiped but since then it has been clear. I took a pregnancy test yesterday and it showed up negative, but later on when I looked again there was a faint pink line where positive would of shown. I am not sure if I looked at it correctly the first time or not but anyway, this morning I took another test and it came out negative. My breasts do feel sore on the sides and heavier and fuller than normal. My question is does implantation bleeding start this late when my period is due? and has anyone had a light pink discharge when they wiped and they were infact pregnant? I am waiting for my period but its just not coming, I took a long hot shower thinking it would bring it on but it hasn't. My periods are very regular also so being late is not normal for me. I do have slight back pain and light cramps and I keep going to the bathroom to see if my period came but its not. If anyone has been in a similar situation or know these answers please help me. Thanks!
