AIBU to think women who are pregnant should at least have an inkling?

[Mummybear8]

I've just seen a post pop up on my FB newsfeed about a woman who has JUST found out she's 8 months pregnant and DID NOT KNOW! I saw a picture of this woman, who looked very obviously pregnant (she was fairly slim except for a huge baby bump...) and I'm thinking; "how on earth, as a woman, did you not come to the conclusion you were pregnant?"

I'm not saying women should know the second the winning sperm arrives and penetrates the ovum (I am equally suspect of these women that "just knew" in the millisecond they created a new life) but surely there's some middle ground between that and 37 odd weeks gone?

I can understand how some women in exceptional circumstances or in their first pregnancies take a while to find out, for example those who continue to have a regular bleed whilst pregnant or those who don't seem to show until very suddenly nearer the middle/end, but seriously? Can't you feel it moving?! I am almost 23 weeks pregnant and have been told I have an anterior placenta and I can still, very distinctly, feel a good kick!

I am especially suspicious of those on their subsequent pregnancies that "just" go into labour all of a sudden with no warning or previous knowledge of this miraculous and totally unexpected pregnancy.
So, AIBU to think that if you know how babies are made, how do you NOT know you've made, and are carrying, a baby?
I am intrigued to hear others stories/opinions...

With cases of a young girl I wonder if she was in denial really.

I taught a girl who had been a surprise when her mother had gone into labour. While she was in my class it happened to the mother again. She was 8 months when she found out. Social services came to see me as they were concerned that, in their opinion, the mother had concealed two pregnancies and did I have any concerns. (as an aside I didn't, the girl was happy, well presented and clearly loved)

U2
THe lass I know had been told by several doctors that she was infertile
she had also been told that the cramps and pain she felt were to do with her form of cancer
and she was a gym bunny so very tight abs

so nothing implied to her that any movement she felt was other than gas / illness

U2theedge 8 hours later I was staring at my first scan showing DD (NOW 11 MONTHS) perfectly forming at 9 weeks!

I think you missed the point. Not knowing you are pregnant until you are 9 weeks pregnant is pretty blood normal and not at all shocking hmm

It WAS (I think I might know) pretty shocking having been told by various GP'S and medical staff I had a kidney problem and had generated not one, but three negative home tests. I think you didn't read my post and fancied a pop missed the point.
