Pregnant after 2 miscarriages and husbands behaviour

I need advice.

Pregnant after 6 years ttc number 2 and 2 miscarriages.

Do you believe there is a way your husband or partner should treat or speak to you ? Husband got home at midnight from going into work to help out for 3 hours ( he'd worked 9 til 5 in the day and went back 9 till 12 )

He was very snappy and short.. asked where phone charger was and I told him in a draw in our room ( the only draw where you'd keep wires / items - all the other draws are clothes ) he continued to ask where in a snappy Manor and I said in your draw ... he then went off on one shouting at 12.22 saying what fucking draw. I explained your draw where the charger always is and he said I was being a dickhead and went downstairs in a mood. He's now accused me of snapping ( yes I'm 14.5 weeks pregnant but I was in a perfectly calm happy mood ) I've told him he's being ridiculous and not to ever call me a dickhead again. I'm fuming.

Why does he think it's acceptable to speak to me like this over something so silly and better yet name call.
