TTC a second time!!

Hey!! I got my nexplinan (implant) out back in August 23 this year. I had regular periods a couple of months before I got it taken out. But I didn't track them. When I tracked August I can't remember what day I started. But in tracked the month of September. If I tracked the august period right. It was 44 days apart. But I was normally 31 days apart before i got pregnant back in 2014 and before I had the implant in. I haven't had a October period yet. I a trying not to be excited yet. My question is how long after I have the implant out will I be able to get pregnant??
