Any moms had benign spotting in multiple pregnancies?

Hi! This is my second pregnancy, 6w6d. First lead to a beautiful now 22-month old baby.

I had brownish/tan/yellow spotting from weeks 4-7 with my first and everything was fine. Found no explanation so said it was likely delayed implantation bleeding.

Yesterday at 6w5d I woke up with brown blood (no clots) that quickly tapered off to tan/yellow. Nurse told me not to worry and could just be something my body does during pregnancy (i tend to have very heavy, clotty periods so it could be old blood).

Has any other mamas of 2+ had spotting each pregnancy that turned out healthy ?
