My husband and I have been TTC for the past week (lol YAY!) and I have an interesting question. Twins run in his side of the family and hits his generations (aka both him and his sister carry the gene and will have the twins). I was told by a sorce that only the female carries the twin trait (which I think is false!). Also, if I was to be pregnant with twins, would pregnancy symptoms be more severe and possibly show up earlier than having a singleton?
