Sonica's right. Try to get him in the mood this am.
I am sorry things didnt work out like you had planned, but you would be surprised by how long swimmers can make it! I am proof of that; my m/c pregnancy we only dtd like 2 days after af left (so maybe cd 7) and
somehow I got pregnant!!

That means they must have made it at LEAST a week, if not longer... So there is hope!
