Baby fever started to go away

I (34f) been trying for a baby for the last 6 years with my husband (38m) and I wanted a baby so bad so we started ivf last year and my body had a big allergic reaction to the meds so I stopped to give it time to recover ( suffer from Lupus) and now we planed to start again in October. But just the thought of trying again make me tired and overwhelmed, I don’t want a baby that much anymore and I don’t know if this is normally. Does baby fever peaks in your 30’s and diminishes slowly after? Am I just scared because of my last experience? Am I overwhelmed by the amount of meds and procedures I have to go through and that makes me not want it that much anymore? Is this normal?
