Very light pink spotting

Stefanie • I`m 28 years old and happily married and have 4 children. 3 girls and a newborn boy!
Ok, so I know that light spotting during early pregnancy is normal. But someone pleeeease help me put my mind at ease that this very light pink (I guess it could be very light brown) spotting. I'm 13 dpo, I am pregnant, I've gotten lines on tests for like a week now. Why am I just now spotting?
