Question???

Jamaica
So me and my DH decided to try for baby #2 and took my BC (implanon) on Sept. 2014. Didn't get first AF until 5 weeks later On October 2014, then again on Nov. and missed AF on December and now 9 wks and 2 days today according to my LMP so my qustion is do i count September as cycle 1 or start on October since that's when i got my first AF after taking my Bc out? TIA
