Will it pass?

Let me start by saying in no way do i wish I wasn’t pregnant. I’m already having a hard enough time. So this is my 3rd pregnancy but i have a 4yr old girl and miscarried my 2nd baby. I’ve always said i only wanted 1 kid and although she was unplanned at the age of 18, she helped me leave her father who was a toxic person. She was it for me, i wanted no more kids. Now i’m pregnant again, and i wanted another girl. I wanted it so bad but when the ultrasound tech said it was a boy, my heart broke. I feel like i can’t get excited about the fact that i’m having a boy. I try for the sake of my family and SO, but i find myself constantly hoping they were wrong and it’s actually a girl (unlikely, i know). I feel so terrible because i’m not excited anymore about this pregnancy. I feel like i’m going to resent my baby once he’s been born. Has anyone else dealt with this? Is it something that will pass when j see his sweet face for the first time? I’m terrified that it wont pass
