Slight exaggeration I'm sure as I'm sure you were actually able to move, whether you felt like it or not.
However, it's about making the right choices to make life a little easier by looking at what must be done, what can be done and what can wait to be done. If somebody has OCDthat bad then perhaps they ought to draw up a list, as above, to manage this.
Any health professional will advice that, actually, if you a take gentle exercise (10/15 min walk will suffice) you will actually feel more energised. It's also about what you are putting into your body to help it to adapt to and support pregnancy.
I have had no choice but to remain active and despite at times not particularly wanting to walk our dog at 6 am of a morning for 45mins, and followed by two other walks throughout the day (whilst working 40+hrs in the nhs) I have no choice due to my husband's work pattern. However what I can say is how much I benefit from this and pleased to say at 34/40 I have had no aches/pains of which I'm sure is as a result of remaining active. Seriously, if you're a struggling, try it - it may work wonders 
A few lifestyle choices that you've probably not considered would actually go a long way.
I also question if you are that exhausted, but have so much to do, why you would spend time behind a computer/mobile device wasting time rather than doing essential things.. the glare from devices/computers alone enhance the feeling of being tired.
Additionally, nobody has said pregnancy would be easier but chances are you've made a choice to get pregnant therefore you have to expect the Rough with the smooth
