So I’m 12 days late from what my “expected” period should of been. I had some symptoms a few weeks ago so i thought i was going to start. Since I didn’t I took a pregnancy test and it was negative, I waited a week and took a 2nd one but that was negative too. Yesterday I started spotting and it was barely anything and I’m spotting again today. Has anyone experienced this? I never spot before I’m going to start my period usually I just go right into it.
