Changing Habits

TTC for 15 months now. one miscarriage exactly a year ago. We gave up "trying" a few months back. it was driving us crazy and we were fighting about why we were not conceiving. we decided to step back and take a breather. Well, my husband brought to my attention yesterday, that i have been busy around the house. I didn't notice it untill he pointed it out, but damn, I guess I have been busy these past few days. also, I have been visiting the potty alot, like 15+ times a day to pee. And i have been craving citrus, and having headaches. Could a change in habit and energy and cravings be a symptom of pregnancy? it's too early to test still. just wondering.
