At week two of pregnancy, there are (at least) a couple of things you may be tempted to worry about that aren't really worth the stress at this point.
First, you may not conceive on the first try -- or the second, third or fourth. This is not cause for alarm. At the age of 20, you have a one-in-four chance of conceiving each month. As you get older, the chances go down. At 39, it's one-in-ten. This is completely normal and doesn't mean there's a problem.
Second, at two weeks pregnant, you don't know you're pregnant, so you may still be drinking that glass of wine with dinner. This is not something to worry about -- there's no fetus yet, so there's no way to do it any harm.
Soon enough, there will be a fetus, and you'll have plenty of behaviors to curb, so sit back, relax and grab yourself one final gob of cookie dough. You may not be eating raw eggs again for a while (or deli meat, or unpasteurized cheese, or quadruple espressos …).
