I don't think I had a very typical experience. I cramped badly, and my doctor gave me a Valium to take before. DH drove me and it was really far from my house - about 30-40 minutes away. I ended up getting motion sick in the car, probably due to the Valium, and between that and the cramping I was just wiped out. Went home and slept for 2 hours and woke up feeling hung over.
Don't let me scare you, though - most people don't seem to react the way I did. But if for some reason you do have a stronger reaction, just know that it does happen. I definitely would clear the rest of the day and not plan on returning to work.
