Go ahead and give it more sun. I have buds on mine , one has 2 seed pods, and it's time to bring them in as nighttime temps are dropping. I brought mine into the garage today, but I think I'll take them back out during the day for a little while yet. If mine get enough light and warmth, they will not drop all of their leaves, and will even continue blooming indoors during the colder months.
and Happy gardening!
