I'm very scared that I'm going to be pregnant just before I go and not know and spend the week at an all inclusive in Mexico.

With my son I took 3 tests and it kept coming negative until the doctor tested.

I want to have a great drunken time with my friends.. if I test and it's negative. . And I have a fun filled drunken week.. and find out I was actually pregnant.. what are the risks? I've read that it would be very unlikely to affect anything so early but I want some real mom advice.
