For me it depends on the pregnancy. My first, my son, no symptoms no nothing until I found out I was pregnant at 13wks. Entire pregnancy no issues, truly a perfect pregnancy. My second, a girl, crazy nausea, crazy emotions and hormones, highly sensitive to smoke, cravings, etc. This is my third pregnancy, my gut tells me it's a girl but I won't know for a long while because I'm only 9.5wks along. My son is my husband's step child so I really would love to give him his own boy but everything in me says this baby is another girl
