The only row DH and I have had was at 17 wks pg with the "other peoples' pregnancies" argument. I was still feeling like shit as my first trimester hadn't fucked off yet, and it was about to merge into the third trimester.
I longed to be sick to relieve the constant nausea. I couldn't stick a tooth brush in mouth without dry gagging. I had barely eaten in 3 months and had lost 3/4s stone from being a healthy starting point anyway, despite visibly gaining bump and going up bra sizes. I'd lost regular casual supply work at 8 weeks when I fainted mid-lesson, then had a panic attack the next day because I had a bleed. Fortunately I finished off the year in a lovely school on a light, part-time timetable where they were very accommodating about me lying down between lessons. I came home from work and crashed out for 2 hours and still woke feeling like death. With hindsight, my pelvis first seized up with SPD a few days after our row and it felt like my lower body had rusted up. I ended up pretty much housebound, but even the GP said it was "pregnancy aches and pains" when at 34 weeks I was in too much agony to go to the supermarket again.
So at 17wks I didn't look very heavily pregnant, and the textbooks said that one should be feeling normal and glowing and that there was this thing called a second trimester whatever the hell that was supposed to be. I still remember yelling at DH that I didn't care what X or Y at work did when they were pregnant and how would he know if they went home and crashed out to recover anyway. My body was not a textbook and was doing its own miserable thing.
The fucking irony is that while I was sitting with my head between my knees tended to by the first aider, DH was in bed with fucking hayfever! DS is at junior school and the injustice still burns
I am pleased to report that such fuckwittery is anomalous to our otherwise happy relationship of 15+ years, that a message did sink in and he is a decent parent with some inititative. Plenty of women smugly parrot that "pregnancy is not an illness" bullshit so its not surprising how it evades some men just how much of a relentless, life-draining an experience it is.
(And the woman who wittered that classic at me could blatantly see that I was hobbling very painfully with SPD at that point )
