After feeling "off" for about a week, and not feeling any movement after feeling flutters around 15 weeks, I called the midwife and she came by and did a quick Doppler check to make sure things were alright. Her finding (which will be confirmed via our sonogram next week) is that I have an anterior placenta. It dulls the sensations of baby's movement and makes it hard for them to find the heartbeat.
Doesn't seem to be a problem for pregnancy, as long as it's not covering the cervix. But, it seems that the likelihood of the baby presenting posterior is higher (babies like to face the placenta).
Does anyone have positive, encouraging stories of homebirth with a posterior baby, or an anterior placenta, or of moving a posterior baby before birth with special movements?
