Question for those who took blood thinners

If you took blood thinners during pregnancy did you notice any spotting toward the end of your pregnancy? I took them with my last pregnancy and didn’t spot but with my current pregnancy I’ve noticed spotting 3 different times now weeks apart. Dr said it was probably the blood thinners but I’m curious if others had this as well.
