I am 15 days late on my period, and this morning I had some light spotting that has gotten a lot heavier. I took a pregnancy test a couple of days ago that came back negative. Is this just a really late period? Or am I pregnant? I have had pregnancy symptoms! I have had random puking, very tender breasts since I have missed my period, had cramps when I was supposed to have my actual period but never bled. Someone please help! I do have a doctors appointment already scheduled for March 4th. I just want some other moms opinions.
