7DPO spotting

Amanda
Ok so I am now 7DPO and 2 days ago I had light spotting and cramping. I haven't had anything since but today saw that I had spotted again and it stopped. AF isn't due for another 7 days. Any input on this? Could it be implantation or is AF being a bitch?
Update::: 
Af not do for 6 days and I am supposed to start taking clomid on day 2 of AF. I'm so confused because idk of those few days of spotting were my AF or not so idk when or if I should start the clomid.
