Fertility question help

Is it safe to start TRT again now that my wife is 11 weeks pregnant? I’m 25. Roughly 2 years ago I was involved in an accident at work where I fell 20 foot landing on my head. I suffered a TBI, multiple strokes, etc. i suffered from horrible horrible hormonal imbalance after. I got on TRT soon after for numbers lower than 60 total TRT. Was on TRT for roughly a year. Became completely infertile. Got off TRT to convince with help of fertility drugs. 4 months later my wife was pregnant. I’ve now been off TRT for roughly 7 months. Recently got my numbers checked and my total TRT is 72. Free is 15.1. Is it okay to get back on TRT injections? Unsure if it’s safe for the child? I’m making do but def feeling the effects of being off the shots.
