Surgery Update/Late Period

GlendaG • Started TTCing for #1 in Nov 2013 Married June 2014 stopped TTCing Dec 2015 now just living
So I have great news My dr wS able to do a peer to peer review over the phone with the Dr for the insurance company and convinced him that I need the surgery and O need all of it so they decided to cover the surgery after all and they aren't making him take out the Hysteroscopy after all. I feel much better now and more relieved. I don't go in for surgery until Mid July now because I'll be on my honeymoon while they have days available before that in June and I wanted to wait until after my period starts in July to make sure I don't get lucky and concieve a child while I get lucky on my honeymoon. 
Since My honeymoon is scheduled for when should be my fertile week next month.
 A little nervous now as I am late this month ( between 3-6 days with a BFN so far )that it will through my cycles off. I didn't chart this month because I thought I would be layed up during my normal window. I really hope this isn't going to be another 45 day cycles.
​This time it feels different though, I'm having crapping and had back pain one day like my period was here or showing up the next day but it hasn't yet.  
​We have decided not to chart again until July so I'm going to fret wondering and/or when I O till then. We aren't going to "try" this month since we get married mid June but I doubt we'll try to not get preggo either. blah I talk a lot. Thanks for listening ladies.
