Life is very different. However, I think everyone's experience is different and you need to find your own path. I grew up in a close family and want the same for my kids. By bedtime (theirs), I find I'm shattered. There is a lot of truly mundane stuff which I absolutely hate and takes a lot of time - the extra washing, tidying, cooking, cleaning etc, but then I'm not a natural at that!
Some babies are Velcro, some are good sleepers, some cry a lot etc, so a lot of what you can do depends on that. Also, some people have grandparents etc close by who are willing and able to offer some help. This makes a huge difference.
I miss the old me and I miss my freedom, I would love to have a glass of wine in the sunshine with a friend, to nip to the gym, to read a book etc, to have the freedom to work late, to not feel so tied. My world has become very small. However, I look for activities, I sometimrs bring a sleeping baby out of a cot for a cuddle, I adore being silly with them, I look up activities to do, pre lockdown we would be out a lot. I hate but accept all the mundane dross that goes with it as the fun we have and the love we have for each other is a much bigger part of it all. My anxiety is huge since having kids - mum guilt, fear of something happening to them, fear they'll be kidnapped, fear for the day when a cuddle and a magic plaster won't make everything ok for them. Just when you're worn down as a five minute trip out takes two hours to get out of the door, one of them will say or do something so cute or funny that your heart is fit to burst again. Whatever they do in life, I couldn't imagine ever not loving them.
Enjoy your pregnancy, enjoy your freedom, as life is about to be very different, but there is a lot of magic in that change and whilst you may miss aspects of your old life or be bored with aspects of your new life, you wouldn't choose to go back.
