(This pic is so stereotypical.. I’m going to paint my nursery mint or turquoise regardless of whether my baby is a girl or boy!) The second trimester (Week 13) I read that pregnancy symptoms reduce drastically in the second trimester and it is true. I got my energy back! I also got back the results of my Harmony test, which screens for the risks of chromosomal abnormality trisomy 21 (Down syndrome), trisomy 18 (Edwards syndrome) and trisomy 13 (Patau syndrome).
