Everyone goes through it differently...
I've got 2 kids already and expecting 3rd on the way.
First child I wasn't so tired, had morning sickness only in the mornings, he came 2 days early with a natural delivery. I wasnt going to take pain meds with him but 2 hrs before he came I needed something, the gas made me vomit so pethidine it was, kinda of worked. Never experienced water breaking with him, contractions woke me up early morning it was like a really bad cramp/ period pain only 10 times worse. He had a meconium birth, where they do their first poo in the sack and inhale it on the way out which can cause problems later on...in his case he's got asthma but it's not bad, only gets bad when he's having a race or gets a cold which sometimes causes pneumonia. As for myself I hemorrhaged after birth , had to stay 2 weeks in hospital before going home.
Second child I was more tired, morning sickness was mostly in the afternoons but wasn't everyday. She came 1 week late and had to be an emergency c section as she was stuck, so epidural was needed and damn that stuff was good, I was sleeping through my contractions. I experienced water breaking with this one, it sounded like a balloon popping followed by a gush of water like turning the tap on. I felt contractions with this one wasn't as bad as the first child. During procedure I wasnt able to see anything it just felt like tug of war, I felt like there was a big hole in my tummy. I was bed bound for a few days, but still in pain even after 2 wks, just getting in and out of bed or sitting was painful. Again had to stay in hospital for 2 wks before going home. Baby turned out healthy and fine
Now with 3rd I'm not looking forward to contractions but excited to meet the little one. I'm not finding out the sex till it's born. Morning sickness with this one was all over the place it could happen at anytime throughout the day which sucked. I'm 4 months now the morning sickness is gone but I'm getting heartburns. I'm hoping for a VBAC (viginal birth after caesarean) definitely prefer natural to c section only because recovery is quicker.
That's my experience.... Hope that helps a bit.
