Long period cycles - worried

I stopped taking the combined pill December 2014 (I'm nearly 32 years old and been on the pill since I was 17) in an attempt to try and get it out of my system and get my period fully regulated so my husband and I can start trying for a baby at the end of 2015 beginning of 2016.  
Since doing this my cycle has been increasing each month to the point that i last experienced a 53 day cycle and now I'm on 62 and counting... I have done pregnancy tests and can fully rule this out! 
Has anyone experienced anything similar? I have a doctors appointment Monday to get results on a blood test, but I'm seriously stressed out and just wanted to know if anyone else has been through this? Keep thinking the worse and think I'm going to be told Im infertile! HELP!
