implantation spotting around Af being due ??

Autumn • My husband & I have 2 daughters & I`m currently trying to conceive our 3rd child after our first miscarriage.
Ladies! Has anyone has spotting around the time of their expected period and ended up pregnant? The day AF was due I had brown spotting and day after nothing! Now I'm wondering if she will even come. Anyone think this may be implantation bleeding?
