I get how you feel, I got pregnant last year in April at the exact same time as my cousin. I had an ectopic which needed hospital treatment, I was in and out of hospital for like 4 weeks, and bled continuously for 9 weeks until it finally went away. A few weeks later, my cousin announced she was pregnant. She had gotten pregnant at the exact same time as me. And there I was, having just finished the aftermath of my horrible ectopic experience, and she was having her viability scan with her baby picture. That stung. It stung throughout the whole pregnancy, and even when she gave birth, made me feel really bad for feeling jealous. But you know what, it's natural. Who wouldn't feel horrible in that situation?
Now that her baby is almost 1, I am finally getting out of that cloud because I see her with her baby and I realise how unique and individual the experience of motherhood is. She's changed so much, a lot of it was hard on her, she's navigating a new sense of self, and it's just been super intense. Not rainbows and sunshine. She's happy now, but like, it's certainly not just a game. And now when I think if I was pregnant and having a baby at the same time, I just know I would have compared my own unique experience to hers, and I don't want to have my child in that situation. Like just imagine the conversations 'Ah my son just said his first word, he's developing so quick!' meanwhile mine maybe hasn't learned yet, now I'm worried and panicking, etc etc. I'm kind of appreciative of the fact that when I get there, I will have someone to go to for support and not for comparison.
Sorry for the long rant, you will have your baby in their own timing and that's what will make it special <3
