Rest rest rest! Please look after yourself NOW! I didn't know I had glandular fever....I now have ME/CFS (chronic fatigue syndrome) 9 years and counting about 15% of glandular fever sufferers progress to CFS.
I would really think twice about TTC with glandular fever- you need rest. Plus you have an infection.
Good quality multivitamin and seeking help from someone who specialises in fatigue will be a huge help. Quality sleep and lots of it. Not sure where you are located but in Victoria there are a few clinics that specialise in fatigue from ALL aspects of your life.
As for the preg- I def had complications TTC ( but obviously my condition is quite different/more severe) pregnancy has been smooth sailing for baby but not for me!!
