If you consider a pregnancy is 40 weeks it seems odd that she gave birth on first of february
Considering the fact that she was pregnant immediately at her wedding night we still have but 36 weeks
So she might have been pregnant and knew it at her wedding since she was about 4 or 5 weeks but then again it does not show at all and there was really no need to wear such a baggy dress either
It can explain the rush because I believe it was his wish to wed in December 1967 and we all know the wedding was a very quick and not very organised or planned one there in Vegas.
