I also had spotting my doctor drew blood on two different days to check hormone levels. It was fine. Just late implantion bleeding. Tell your doctor yourfears and have some tests done
If it is just spotting you are fine.... If it is more like period, go to ER to test HCG and have u/s.... All the best
It could be, or it may not be. When i had a blighted ovum it started off with brown/light pink spotting, and then just got heavier. The only way to know for sure is to go and get checked out at the hospital or your doctor if available. I also had a couple of days of light pink spotting with this pregnancy from late implantation bleeding.
