I agree with everyone else. Someone told me once that yesterday doesn't matter, that all we have is today. They are right you know. Please don't beat yourself up about it. It will just create a viscious cycle and you'll want to do it again. Be nice to yourself. Take a hot bath or do the same things you did before to get the 18 weeks. Remember what you did? How you got from day to day? What did that feel like?
