35 day cycle buddies?

Anyone else TTC with irregular cycles?  This will be #2 for me and it's so frustrating because before I had my ds, I was super regular to the day, but now my cycles are longer and period are shorter/lighter.  I'm also about 50lbs heavier this time around too, and coming off BC as of early Jan.  I started opk this past month and only got a positive 1 day so not sure what that means... But I'm looking for CB who might be going through similar situations to commiserate and hopefully get BFP's! :)
