Just found out I am pregnant (only literally 4 weeks) I kind of thought I may be but did an early test last week which was negative,so I drank lots Saturday night and then was a few days late with my period & have now had a very feint positive,its definitely positive but I am worried about the alcohol I drank!! I won't drink from now on but I didn't really believe I would fall first month!!!....Does anyone know the effects this may have on development?
