I feel your pain OP. Why do they do this WHY? 
No matter what I complain about, my husband always has something similar (or worse!) And rarely does a week go by without him complaining about SOME pain or suffering he is going through.
And every other month, he develops a new ailment. Despite many visits to the docs, and various specialists, and having many tests (at clinics and hospitals and so on,) they have never found anything wrong with him
And when we go to stay in a hotel or guest house, we have separate rooms, coz he snores something awful, and every single time we go anywhere, my room is ALWAYS better than his, and his room is SHIT. 🙄 He finds fault after fault with it, it's always more noisy, it smells funny, it's too cold, it's too hot blah blah blah.
I say 'let's switch rooms then!' 'Oh no no no I may as well stay here now....' he says ( passive-aggressive martyr alert. )
Like I said WHY? Why do they do it? Is it an attention seeking thing? Do the not like someone else being more 'ill' than them? Or in more discomfort??? 
I do love him, and we have a good marriage, but this side of him pisses me off!
Not gonna lie, I feel better knowing many men are the same.
You have my sympathy @Icouldnot and congrats on your pregnancy!!!
