I can so relate to that!!
Im not even pregnant and I cried my eyes out watching Marley and Me!!!

Im a crier anyway though - not sure why - I burst into tears listening to songs on the radio, ads on TV, I was uncontrollable tonight watching Desperate Housewives, I cry for no reason at the gym watching video clips and running on the tredmill! lol

Cant say Ive ever made myself vomit though

The worst was definitely watching The Notebook 4 months pregnant....that was not pretty - I was crying in the first 5 minutes!! Made DH cry too though so I felt better - I could cry with abandon! rofl
