Jenna then stopped what she was doing, her body was a little weak and she needed a little rest. Her pregnancy was now in her second trimester, but the fatigue she felt was like being in her third trimester.
Ryan ever explained about it. It would be natural for something different to happen to a woman's pregnancy in general, because Jenna has an illness that probably hasn't gotten better yet.
Whatever miracle he experienced, it did not mean that he had escaped from a critical period of his illness. Because what usually happens is that disease is like an enemy in a blanket, a silent killer, like heart disease that many people don't realize.
That's why Ryan warned Jenna to take care of himself while Ryan wasn't by his side, and at the same time asked Clara to watch over Jenna.
