Help!!

Hello! 

So, I have a question for you all! 

My partner And I are trying for a baby and I came off my mini pill in Nov and have had normal cycles since. 

I am due for AF in 5 days however I have just started having a light bleed. It’s nothing like what my normal period would be like and it’s a very little amount. Could this be implantation bleeding? I do have a very mild cramping pain too and feeling very tired and generally run down. 

Any advice would be much appreciated!
