So ladies I’m confused I took a pregnancy test and got a faint positive and what not on the 14th. The 19th I had pinkish discharge with light spotting then it got alittle heavier but much lighter than my regular periods. That lasted for a day or so, and had brown discharge for a day or so.... I was told it was implantation bleeding but it was 7 days after my AF was due and I bled lightly for about 3 days the brown on the 4th day..... I’m confused?? Doctors appt tomorrow. My periods are never late in my entire life.....
