Strange start to AF, thoughts?

Okay so I am in my 4th cycle since stopping BC. AF due 10/31, no major symptoms until last night when I had very minor cramping and one wipe of red blood. So I thought AF was here. I have never spotted on or off BC, once I start I start and its heavy with bad cramps and lower back pain. I have had no cramps or bleeding since yesterday. Should I wait to tell glow AF came? My mom said she had light cramps and bleeding with both me and my brother....could that have been implantation? I'm 13DPO today.
