Power of brain question.

So this is a bit crazy. I'm 32 now.  I didn't want children. When I started dating my now husband, he wanted family. So I knew from the beginning I would have to change my mind and try to have children with him. My periods were semi normal at the time. Around August, when the wedding was getting closer my cycles went nuts.. 60 days, 54, 45 days long. I went to my obgyn and she tested for thyroid, premenopuose etc. She couldn't find anything wrong. She said I appear very healthy and fit and she has a suspicion I may be subconsciously messing up my periods to not get pregnant.. ! We got married in January and now ttc. I knew from months ago that this will happen and thought about it constantly and stressed out about how different my life will be with a kid.. I love to travel, I play sports, having children seemed like the last thing I was interested in.. But now I understand it's just the next stage in life, all my friends are mothers now, and with my amazingly supportive husband I'll be fine and probably happy once it happens.. But of course, it's almost impossible to get pregnant when your cycles are 45 to 60 days and you never know what's happening and when..  My husband also believes I just need to relax and he is signing me up for acupuncture. Do you guys think that makes sense? Can that really be the reason?
