I have had 2 beautiful girls. With DD1 i was sick from day dot til i gave birth. I was even admitted a couple of times from dehydration. I was sick 24/7. I was worried about how i'd go with having a toddler and pg but thought well i want more kids so now or never. With DD2 i had MS from about 8 wks til about 23 but nothing compared to DD1. I personally dont think the sex has too much of an impact as i had 2 girls and 2 totally diff types of MS. With DD2 though i had other complaints such as back pain etc so each and every pg is individual.
