Implantation bleeding

Does anyone know if anemia can cause a heavier than normal implantation bleeding? I bled for about 3 days. First day very very light and pink the second day was heavy and so was yesterday. It ended up slowing down to only showing up when I wiped again and it was pinkish brown. With my second child I have bright red implantation bleeding (the doc agreed that’s what it was) I’ve currently moved and have to find a new ob which is the only reason I’m asking on here. I’m also getting some test later today but I don’t know when the best time would be to take them.
