This novel might be 'A Doctor's Assessment' or 'A Doctor's Growth.'
My answer did not seem to match the question. According to the knowledge I've learned from online novels, there's never been a plot where the male protagonist would fall ill on the 15th of every month and could only be relieved by hugging the female protagonist. This could be a misunderstanding or the question was not accurate enough. If you have any other questions, please feel free to let me know. I'll do my best to answer them.
This was "The Story of a Fake Female Companion to Cultivation". The female protagonist traveled to ancient times and was poisoned by the waiter after seeing someone in an inn.

This plot was quite common, and it usually appeared in some novels or television dramas. The male protagonist might have slapped the female protagonist because he thought that the female protagonist had done something that the male protagonist was dissatisfied with or that the male protagonist had suffered some frustration and disappointment, and then the male protagonist had done something extreme. The female lead's miscarriage could be because some of the male lead's actions caused the female lead's safety to be unsafe or the female lead had some illness that needed treatment, but the male lead did not realize or did not care for the female lead. In this plot, the awakening of the male protagonist was also a common turning point, indicating that the male protagonist began to reflect on his actions, recognize his mistakes, and strive to correct them. This kind of plot usually makes the novel or TV series more fascinating, allowing the reader or audience to feel the growth and change of the protagonist.
