HI.I had what I thought was my period on jan.3rd but it lasted only one day and was light.since then I've been sick,my appetite has changed,I've had to pee a lot more,I've been tired,and my breasts are tender.I took a test 2 weeks ago and it was negative.was it too early then?I'm due for my period to start on jan.31st.now today I had a little spotting.really just a couple spots that were pinkish red.could I be pregnant?was that spotting implantation? HELP!
