I am going to get the book I am going off the pill at the end of the month I am tired of the side effects, we are going to TTC in the fall so not a big deal if happens sooner. I did talk to my obgyn; I am on Yazz and he said the pill is out of your system as early as 24 hours, I orig. thought I would need to go off a couple of months prior to TTC but he said no.
