For the last couple of days I've felt extremely fatigued. A walk across the landing leaves me weak and breathless but I have no other symptoms. After 4 years TTC 4 CPs PCO, a largish ovarian cyst and having to repeat ALL my fertility tests due to the results getting 'lost' I'm not a symptom spotter by any means. I stay positive(most of the time) but I try not to get my hopes up. But at 10 DPO would I be too early to be fatigued? Could it be pregnancy or is it just a mystery illness? I've never felt like this in my life.
