Last night me and my husband bd, however I drank heavily. A bottle of wine, half a bottle of rum, and a bottle of beer. Now I just read that heavy drinking can cause you not to conceive. However with my first I drank every day and the night before I found out I drank just as heavily. My pregnancy was healthy, just constant throwing up. Right up to the day I had her. My question is does it really affect conceiving chances are just affects the baby when you have conceived?
