Hi all, sorry for a depressing post. My period was due on Friday. I had what I now suspect was a very light implantation bleed. I mistook this for the start of my period and that evening I drank two glasses of red wine - approx. 4 units. I am beside myself with guilt and upset. I’ve wanted this for over two years and now I feel like I’ve messed it up completely. I’m veering between trying not to worry - it’s not like I’ve been drinking bottles of wine, it was only two glasses and a complete once-off (I’ve stopped now), but I’ve also read studies saying even a small amount of alcohol can negatively affect the pregnancy. Apparently the day I drank - around day 17 - is crucial to very significant development. I’ve read lots of threads where people say not to worry, as the embryo doesn’t share a blood supply with the mother until later on when the placenta develops, but I’ve researched and this is simply not true. Alcohol can pass through the yolk sac. I’m devastated this has happened. It was so preventable and stupid. This baby is so wanted and my first, and now I may have damaged it! Please be kind.
