Girls, a little question. I’m 18–19 weeks, and I feel the baby’s movements low in my belly, really very low ))) Has anyone experienced this??? Does it mean the fetus is positioned low? Tomorrow I have a routine appointment with my gynecologist, and on the 14th I have the second ultrasound screening — I’ll know for sure then )
