I've been told that I will have an U/S at about 23 weeks to check on placental blood flow. The OB said the blood flow to the uterus is a different waveform to the blood flow waveform of the placenta. At 23wks they will be able to see what the waveform looks like and determine if the placenta has properly implanted. I will still have U/S every 2wks after that (regardless of the result) to monitor fetal growth. He says there are specific changes that occur that indicate fetal insufficiency and they will monitor for those changes throughout the pregnancy. I think part of it is reassurance for me (but that is great!!) but also because they know more and can intervene earlier to minimise the risk of fetal death (like this time).

All I need to do now is get pregnant!!
