Womanly issues was a theme of this season which I expect will diminish going forward, just by knowing the rough shape of the plot. We've seen live births, a stillbirth, and now a miscarriage. Not saying they were looking to check all three boxes but dramatically it underscored how much weaker Rhaenyra is at the start of this whole thing, not only physically but in terms of House support, experienced dragons and Dragonriders, her legitimacy contrasted with Aegon II's, etc. She also loses her father, her (unborn) daughter, and her son this episode, which builds sympathy in the audience going into Season 2 where I expect she's going to let loose The Bells-style.
But slowly, she starts gaining strength and power over the course of the episode, starting with her cremating her unborn daughter (the ashes of the past) and continuing to her receiving her father's crown (as Aegon II wears Aegon the Conquerer's). Her new power is tempered by her memory of Viserys, and I also think the show is subtly commenting "Hey women would probably make better rulers" (see the bridge scene redux where Rhae reinforces to Otto for a second time how she alone is able to end an assured conflict without spilling blood). This second instance was also preemptively reinforced to Otto by Alicent taking charge and telling him not to murder Rhae -- he calls it "[womanly] squeamishness," but this episode showed to him how the two women trying diplomacy might just work.
Then Vhaegar has to go and start a whole Dance or something.
