Hi gal,
Just some words of encouragement for u: I was in a similar position, finding it hard to exercise due to work commitments..but after reading that having a fit and healthy body would improve my chances of success, I forced myself to go for either a quick jog or long walks at least 3 times a week. Hence, after failing my first fet, I had 3 months before commencing my next fresh cycle. During this period, I was more hard-core about eating well and exercising. Everytime I felt tired or reluctant to go for my exercise routine, I asked myself this question: do u want a baby or not???!
Obviously the answer is a yes, so I would drag my butt off the couch (very difficult task after 9-10 hours in the office!)
I'm now 16 weeks preg, so u can do it! Just need to remind yourself of your long term goal ie cute healthy baby
All the best!
