Cousin's wedding in Mysuru in November, and my side of the family will not take it well if we skip it. I'll be pregnant but nowhere near the end. My doctor is fine with travel in general. The practical question is which way people found easiest: a long drive with stops, an overnight train, or a flight to Bengaluru and then the road. I get queasy in cars.
Your doctor's view counts for more than mine here; I look after children, not pregnancies. As a parent who has done that trip a few times: the Bengaluru to Mysuru stretch is the easy part now. It's getting out of the airport and across Bengaluru that tires everyone. If cars are the problem, an overnight train may be kinder than a flight followed by three hours on the road.
When my partner was expecting our daughter we took an overnight train to Ahmedabad for a family function. Being able to lie down mattered more than the total hours. If you go that way, book a lower berth early; in wedding season they go fast.
Keep going
