Am I being silly?

So I’m 14 weeks along with my first. I’ve been with my Fiancé for going on 3 years and he has an eight year old daughter.

The experience is for the most part smooth despite having fibromyalgia. But there’s one thing that completely grinds my gears...

whenever I have cramps, or a moment of hormones or am so tired I can barely stay awake (which doesn’t happen often). If my stomach feels like it’s it’s stretching out or am just generally in discomfort because I’m a small person with a physical illness (as well as mental but I’ve been good about not letting that affect me as much as humanly possible) I hear the lovely phrases “you’re still early in the pregnancy”, “just wait til later”, “you still have a long way to go” and the topping to the ice cream “when (step daughters mom) was pregnant it was like (insert story)” from my fiancé.

Now, I’m not stupid by any means I know the further along I am the worse it’s going to get but that in no way takes away from what I’m feeling in the moment nor does it take away the discomfort I’m in when I’m in it. And on top of that every woman goes through pregnancy different because the bodies are different and I feel these statements almost completely invalidate what IM going through in the moment. He’s supportive in every other manner- makes sure I take my prenatal, asks if there’s anything he can do like cook dinner and what not but when it comes to this- he has the simplest mindset that because I’m “only” 14 weeks the pain or discomfort I find myself in is invalid because it’ll be worse later.

Is that selfish? Or silly? Am I being irrational for getting agitated whenever those phrases are uttered?
