Any hints for conquering fatigue?

Hi all, I’m 36 and on my third pregnancy (no children yet) and I’m currently 7.5 weeks, the much anticipated first trimester fatigue has set in on a monumental level. Before becoming pregnant I ran about 4-5 miles every day on top of doing functional weight training sessions several times a week. Due to my previous pregnancy losses, I decided to forgo running until later in the pregnancy (it’s coincidental I’m sure, but my miscarriages bleeding always started after running). I was managing at least 10k steps a day and 30-45 minute functional weight training until about 6 weeks. I am lucky if I can get 8k steps in a day and weights, I just don’t have the energy. I’m also eating more, trying to make sure it’s healthy stuff but I’d really like to maintain some level of physical fitness even right now to negate preeclampsia and gestational diabetes.

Any suggestions for working through the crippling fatigue? I work about 8-9 hours a day too so it’s hard to break up workouts.
