I'm sure everything will be just fine
Medicine's a strange thing- they overcomplicate things most of the time!
I do know that all babies start out as girls by the DNA- and that some point in development the "boy" chromosome takes over and turns it to a male- I've read that somewhere (not sure where)... so that may be another reason why it's showing male and female DNA? (I don't want to sound like a weirdo but I really have read or head that somewhere! lol)
I'm sorry you have to go through all of this- just try to take it easy and not stress out too much. I know it's hard to do, and you're probably sick of hearing that but you should try to stay as stress free as possible, for yourself and the baby. I'll continue to pray for you and your baby as well!
