Periods and my SO

So, my SO lives 2 miles away from me and doesn't have a car. There has been stress going on in our lives pertaining to our relationship, which triggered my period a week early. I recently got my jaw shattered, when that happened he was the one I went to for help, his dad drove me to the ER and then drove him down directly after he got off of work, he hasn't been getting much sleep due to this and it's worrying me. Seeing as I just started my period early he's also getting up early and walking down to my house every day and dealing with work and school. I know this isn't healthy for him and it's started to noticeably effect both of us physically. Any tips on how I can make him feel like it's okay for him to take some time to care for himself?
