Break up-first trimester-am i hurting the baby by stressing?

My bd and I broke up and since I’m still in first trimester and my emotions have been everywhere lately I was a complete mess. The breakup wasn’t valid and there was no reason for it to happen he just thinks I cheated on him when I didn’t and nothing is changing his mind from the thought that i cheated. I posted earlier and I’m just putting the screenshot in cuz I want to remain anonymous as all of this is really embarrassing and I don’t want to show my face

I didn’t add in that post .. but I’m 8w+4... ive been under a lot of emotional stress today because of everything. I’m afraid I jepordized my child and I’m nervous. When I woke up this morning I was very very nauseous I haven’t really been nauseous yet so i was thinking maybe I just started getting this symptom.. but then an hour later I literally started pissing out of my ass.. gross tmi sorry... it only happened twice in the span of an hour and I haven’t had diarrhea since. But it just makes me nervous that all this stress can affect the baby.
