CHONGQING - A 26-year-old Chinese woman lost her unborn baby after staying up for four consecutive nights to watch World Cup matches broadcast from Brazil, local newspaper reported on Wednesday.

Xiaolan, who was around two months pregnant, suddenly felt a sharp pain in her abdomen when she was watching the game between Germany and Portugal Tuesday morning, the Chongqing Evening News reported.

She was then rushed to the hospital but still suffered miscarriage, the newspaper said.

This was not the first sad news since the World Cup kicked off last Thursday in Brazil.

According to reports, three Chinese soccer fans have died after staying up all night to watch World Cup matches on TV.

Despite the fact that Chinese national soccer team only played in the World Cup finals once, in 2002, without scoring a goal, China never lack soccer-mad fans who usually pick themselves a second "home team" from the world's top teams. Brazil, Argentina, Germany, Italy, Netherlands and England all enjoy huge fan bases in the populous country.

During the group stages, the World Cup matches take place at midnight, 3 am and 6 am Beijing time.
