I was so excited because today I am three days late for my period. For the past week or so I've been feeling crampy (similar to menstrual cramps). Then this morning I noticed a very small amount of brown discharge. I took a pregnancy test and it said negative. My heart is broken. I truly thought this was my time...is there any change it could be implantation and I could still be pregnant with a negative result from a urine test? Or am I just grabbing at straws?
