Panic get the plan B

You have no idea how long you are going to be in this body, maybe forever. But however long you are you don't really want to be pregnant. You head down to the pharmacy and talk to the nice man there, he tells you that you should have come as soon as you had unprotected sex but that it is still effective for up to 72 hours, though less so the later you do it. You buy the pill and take one right there with a coke you buy at the same time. The next one you have to take in 12 hours right before you go to bed.
