I can honestly say - and I don't care how cheesy this sounds ... having children is the best thing that's ever happened in my life... I love the bones of my husband but I love my children even more. I would die for them - literally would take a bullet for them ... again don't care how cheesy that sounds. 
They are just over a year apart, and the first one of two years were a little bit difficult with sleepless nights, shitty nappies, bedtime accidents, having to get up at 6:00 AM every day till they were about 2 and a half to three, and trying to juggle work and caring for older family members. (I worked 28 hours a week at the time.) They were good babies/toddlers, but it was still quite hard work. Got lots of love and cuddles and fun back from them though, so totally worth it! 
From about the age of three or four to about 15-16 it was just the best years of my life ... I went very part time when they were was 6 and 7 - for ten years - like just 16 hours a week, and had the best time... day trips, picnics, beach days, holidays, painting and baking and crafting days, cinema and theatre trips, and had just the most wonderful life with them. (Sometimes me and DH and the two of them would do stuff, sometimes just me and them, and sometimes just me and one of them... Me and DH did stuff alone too occasionally...)
Age 16 arrived... The college years and early uni years .. They were a bit difficult at times. because they were both very defiant and they wanted to do things they were too young to do. They were just little shits to be honest with you 😆 But once they reached the age 20-21 they became their normal non-teen selves! Both in their late 20s now - they've just become the most wonderful amazing young adults and they're just golden ...I absolutely love them so much I could cry.
Once again I don't care how cheesy that sounds 😆
As quite a few posters have said though - if you're not sure - and you're on the fence then don't do it, and you definitely can't do it unless both partners are on board. Me and my husband were in our early 30s, when we had ours and we'd been married for several years. We both desperately wanted kids almost at the same time - it was really strange ...
When we got married we didn't say no kids ever, but we weren't that fussed. Didn't have any plans for any age to have them ... Then several years into the marriage I was knocking the door of 30, and I said to DH 'you know what - I'm getting kind of broody - what's that about?!' DH said 'so am I - how weird is that?!' It was perfect timing. I came off the pill and was pregnant with our first within 3 months.
As I - and many others have said though @Addictedtocinammonrolls you do have to be absolutely sure. And so does your partner.
