Frustrating +2ww when irregular

Sara • Identical TWINS? what? How'd that happen?
Not only am I irregular, I decided to up my exercise routine and start personal training at the beginning of my assumed 2ww (based on BBT). I'm 14 dpo - test this morning was negative. Only symptoms of AF or potential pregnanct is really sore boobs which could probably from the bazillion push ups and chest presses my trainer insisted on Tuesday! 
The joys of being irregular!
