advice?

I got my dreaded period today. I'm heartbroken and devastated. My SO was at work when I found out but I didn't tell him anything. wanted to wait til he got home. When he got in, we talked about everything else but the AF. I just couldn't find a window of opportunity. as it stood I was visibly agitated, depressed, moody. he didn't seem to notice; If he did he didn't say anything. Then we're watching some programme on Netflix. finished dinner. I'm upset, he's talking about work. then it's like everything exploded from there!! A mess happened which I was upset about because I had cleaned house. our cats got into things and broke something. more frustration. SO didn't clean after himself. Now anger. this happened in maybe an hour. Now he's in bed asleep, presumably upset and unsure about me, and I am exhausted unable to sleep because I don't know what to do. I'm heartbroken. this TWW was more emotional than usual and tonight was like the nail in the coffin. what should I do?? I am beyond exhausted and I fear an emotional breakdown if I go at this wrong.💔😭
