Hi OP, just offering my POV for what it's worth.
In my first pregnancy I was happy to be preggo, no expectations around sex of baby. Found out at a scan that it was a boy, great, knew we ideally wanted 2 dc so no biggie. Gave birth and loved my boy to bits.
Cue second pregnancy, my last due to finances, age, and general life choices. I was hoping it would be a girl. Was super close to my mum who died when I was young, grew up close to my sisters, majority of my friends are women - I would have loved a mum-daughter bond of my own.
It wasn't to be, and dc2 was also a boy. I didn't weep or scream or have regrets, I was just a bit gutted that I'm never going to have that relationship. I think losing my own lovely mum made it a bit sharper, maybe? But ultimately I felt very blessed for my healthy second pregnancy.
When he was born I also fell in love with him and would NEVER have swapped him (although hilariously we were in the recovery room with a couple having their second girl and the dad did make a joke about swapping the babies! Like the universe was testing me!)
But there are still tiny moments - shopping for lovely dresses for daughters of family and friends, watching them play with their dollies like I did while my boys are yomping and yelling! - and I think it's possible this will go on as they grow up: periods and prom dresses and first loves!
But ultimately I feel so lucky to be a mum to 2 fab healthy kids, have plenty of friends who struggled with men or fertility or both. I know I'm one of the lucky ones! The 'disappointment' is never enough (for me) to derail the love and luck I feel every day.
Wish you all the best.
