I am pregnant with baby number four after three girls! I didn't find out with my first DD, and it was such a shock to me that she was a girl not the boy that my instinct had told me (ha)
The second time I found out, and I felt uneasy that they were wrong, I could not relax with what the sonographer had said. I checked at 35 weeks again and finally could relax that she was indeed a girl.
After baby two I decided never to find out the sex again, it didn't mean that I am not as curious as can be, but I found it much more fun not knowing what the baby was. We didn't even look at the gender until DD3 was over 2 hours old. It was such a joy to inhale her for two hours as our adored new family member and not know what she was.
THis time people have nearly driven me mad guessing what this baby is, everyone is a professional baby gender guesser!!! I has a moment in the ultrasound where I was weak at the knees to know, but I had already asked her not to tell me, and she was not going back on her word!! THis time we will again just enjoy baby time before we look at what gender the baby is, I am not sure how long that will be, it was clear when it was time to look last time so I will trust that again this time.
