Wife has been on progesterone and estrogen drugs related to her IVF treatment. She is now pregnant but will continue to take the medications for another month.

Things are usually fine, but once in a while she suddenly gets in a dark mood and sleeps for hours in the middle of the day. This is related to the medications she is taking, since it never occurred before taking them. Not really sure the best strategy to deal with that, whether I ignore it and let her recover on her own, or compel her to get more active (basically would have to lift her out of bed). Dr. just said 'people can get moody'.
