I drank 2 drinks per day for 5 days straight on the 4th week (client mtgs)- i obviously didn't know i was pregnant. at the end of that week i got my bfp. I'm anxious because i see so much conflicting info out there. One view is that beg of week 4 is the embryonic period, which is when mother's nutrients pass on to the embryo, which means high risk for Fetal alcohol syndrome (which can't be detected in prenatal tests apparently) Another view is that upto week 6 embroyo gets it's nutrients from the yolk sac (no clue where the yolk sac gets it from) vs. getting in from placenta, which only starts working after week 6. When i asked my doctor, she said as long as you've stopped drinking now - that's all that matters. This keeps me up at night anyone else go through the same thing?
