Hi everyone! So I am suppose to be getting my period in a few days and yesterday I felt like what were period cramps. I noticed a little bit of light pink when I wiped. So before I went to work I put a tampon in. A few hours later I noticed when I took the tampon out it was about a quarter size amount of brown blood. I have never experienced this before any period. My husband and I have been trying. I took a pregnancy test it was negative yesterday as well as this morning. Any thoughts ? I still have light cramps throughout the day as well.
