Spotting 4 weeks

Tina • Mommy to 3 fur babies 🐶🐶🐶 expecting our first baby 5/31/18! 🍼 Super excited & can't wait!

I have been spotting just light pink & brown and very light but daily since last Thursday. Thursday is my estimated implantation day. So I assumed that was the spotting originally was from...however it's now been 10 days and I'm still spotting. I'm 4 weeks & 2 days. No cramping or anything abnormal. I called the dr and they told me it was normal and nothing to worry about. I see them for first appt. at 8 weeks. Has anyone else spotted like this for a week or longer and was absolutely fine? Thanks!
