No its impossible. God made us to know that we are with child..it cant/doesnt happen. People just want an original story to tell!
Not everyone is the same. Some people dont get symptoms at all! I Totally believe you! My uncles gf didnt know she was pregnant until she gave birth to a baby girl! And she was tiny and thin as a stick lol!
Hey, so im 20 and have a 2 year old daughter and im 35 weeks pregnant with my son. I dont want to dis you, but I dont believe you. There is no possible way to not know youre pregnant. Im a small person too and our bumps show 5 times faster than others who arent so small first of all. Second, the baby is moving A LOT and kicking hard by 30 weeks, even sooner really. Your boobs get bigger, you get sick, your stomach will definatley show unless you weigh 200+ lbs, then probly not, and again you can feel the baby. You arent being honest..and really? Its been done before and disproven. You cant not know youre pregnant. But good luck anyway.
Congratulations on your pregnancy! What a roller coaster ride you must have been on over the past few weeks. I am 37 weeks pregnant with my 2nd so I will share what I hope will be reassuring to you.
It sounds like you are worried about labor pain. Labor hurts, and it is hard work, but we are built for it and the pain has a purpose. The thing that I didn't expect was that the labor hormones are just as strong as the pain--some people call it "laborland"--you kind of go into an altered state. It's not like having a massive headache or a sprained ankle--it's part of a natural process. Try to forget everything you've ever seen in the movies and on TV! Labor can be very calm and focused and each contraction gets your baby closer to being out. Before 3-4 centimeters I found the pain very manageable, like bad menstrual cramps, roughly.
That said, there are pain relief options if you feel very anxious about the pain. You should talk to your doc/midwife about these. My epidural was painless and worked well to ease the contractions pain. (I am going to try to have my next baby without pain meds because I had some epidural side effects last time.)
My only other advice would be to find a good labor support person to be with you in labor to comfort and reassure you, and to help you after the birth, if possible. And read a good pregnancy book--like "From the Hips--" too. Good luck!
