Explaining to husband?!

I’m 31 weeks now in the last, and most complicated, pregnancy I have had. This is his first child, but my fourth.

Lately I have been stressed out, possible diabetic then when I was cleared of that my blood pressure was found to be 180/80 with protein in my urine. The doctor is slightly concerned about preeclampsia, which I may have had (undiagnosed) in the previous pregnancy.

Anyways, due to that and a stressful job/financial problems, I have been more on edge lately. He does not argue so I have just been shutting down more.

How can I explain to him that I have lots of pregnancy hormones that make me be on edge, plus the added stress of regular life?!
