I didn't know I was pregnant aka toilet birthing

OMG, seriously, I about fell off the sofa while watching a show on The Learning Channel last night. At least, I am pretty sure that was the channel. With 200 to choose from on cable, I am already too old to remember.
There were three episodes of this special about women who gave birth in toilets and in random places because they didn't know they were pregnant.
WTF?
Sounds like most of them had an irregular or no cycle. Fair enough. However, at nearly 4 months pregnant, with the worst yet to come, I want to know how none of these people noticed changes in their body?
Seriously, I have felt so bad some days that, had I not known, I would have thought I was terminally ill. The stabbing pains in my boobs would be enough to, at the very least, make me go see the OB/GYN.
There was a woman who had her baby at a campground in the bathroom. She bent over to have her other half check to see what was coming out of her and the fool thought it was her intestines and told her not to push.
I'm not a doctor, but if my intestines ever start sliding out of my vagina, I seriously doubt I would be standing bent over asking Mr. W to have a peek. Writhing in pain on the floor, maybe.
This tool ran off to call an ambulance while the woman proceeded to push out a baby onto the concrete floor, directly onto its head. Why, when it started falling out and she realized what was happening, she didn't try to catch the poor thing, I don't know.
I was startled to see that all the parents featured here actually got to keep their kids. At the very least, you might think this would show evidence of some form of incompetence?
There was a picture of one girl in a bikini 2 months before she delivered(about a month early, if I recall correctly) and she was still very thin. To be honest, I wish I looked like that before I was pregnant. It made me wonder where they hide these babies? Most of the rest of them, I admit, were bigger women, but two of these women had TWINS.
Seriously, there's one for you. You go to the hospital and leave with 2 babies and had no idea they were hiding in your belly? Did they think that was just the Hostess snacks kicking them?
What disturbed me the most were the babies born into toilets. How do you tell your child they came into this world in the toilet?
Despite all the odds, the babies all were born healthy. I think this just goes to show you that all the prenatal care in the world can't promise you a healthy baby and that my baby should be fine despite the fact that I still really enjoy my coffee everyday, have eaten lunch meat with preservatives whenever I want, and got the baby drunk on jello shots about 2 or 3 weeks after it was conceived. Don't blame me. These people were clubbing and camping and dropped their babies on their heads and into the commode and they came out fine.
Miniature humans...they're resilient little things.
