I had light pink spotting 4 days ago... very small amount and nothing else.. then I thought maybe it was implantation so I took a pregnancy test and swore I could see a faint line. Then I took a different test and didn’t see the faint line. Now this morning I just had more discharge so I’m confused. My period isn’t very regular but I believe I started on the 4th or the 5th on January. Please give me your opinions!
