Well, let me see...
highs for all 4: short labors. The longest one was 6 1/2 hours.
#1 LOW-finding out I was pregnant (in a fairly new relationship and not married and that's not the way I wanted my family to begin), first trimester morning sickness, having the flu during delivery
HIGH- when my SO (now DH) finally accepted the fact that we were going to be parents, her birth-2 pushes and she was out. She's beautiful BTW...inside and out :-)
#2 LOW- my DH being on deployments much of the pregnancy
HIGH: it was just an easy pregnancy....she however has learning and emotional disabilities so I think the easy pregnancy was God's way of giving me a break before the tough stuff began.
#3 HIGH-finding out I was having a boy after 2 girls, delivering him
LOWS- where do I begin..... he settled on my sciatic nerve early in the second trimester and stayed there, he kicked me so hard that part of my uterus was pinched (it felt like he had his foot in my ribcage til I gave birth), Edema, loss of taste buds, my right arm continuously pulling out of it's socket at night, near nightly leg spasms, he was 2 weeks late and my third trimester was in the summer-in Virginia- during a huge heatwave and we didn't have AC...i think that's all :-)
#4 HIGH- finding out I was pregnant with him. He wasn't really planned but after he was born I felt so complete.
LOW- DH wasn't here for his birth. He missed it by 5 hours. Thank God for good friends though :-)
