I say that symptoms for each gender are very real. I mean you are making a male or a female. The hormones are not the same in you. I would think? I have three boys and a girl...
Boys: I was never really sick in first trimester just here and there. I had facial hair BLACK! on the sides of my face from about 7 months on! STOP LAUGHING! horrible... huh? I did have the classic basketball belly with the first two. But, the last little guy came just 20 months after brother and I was too fat to detect any real shape!
Girl: I was so very sick, I could only eat a certain type of bread. I would lay on the couch on my side sleeping for hours. I was knocked out with that PG. I had a pretty good gag reflex. The smells were stronger with her pregnancy than all others. Last off PIMPLES!!!!!!!!!!!!! SPOTS!!!!!!!!!!!!! all over yuck yuck! oh and my belly was around not up front too, I lost my waist with her, and not the boys, it was defined with curves on the sides even into 9th month.
