More than 3,000 women and girls are believed to have been given the birth control pill in the country.
But the government says it needs more data.
Read moreAt least 3,722 women and 709 girls have been treated in emergency clinics across the country since January 1 for the use of the birth-control pill, the Health Ministry said.
More than 3 million Filipinos have taken the pill since it was launched in the Philippines in 1996, but the government said the total number of pregnancies in the Republic of the Philippines stands at 627.
There are about 6,000 emergency clinics in the state, and some 1,500 more are under construction, it said.
The number of abortions is also on the rise in the capital, Manila, where more than 2,500 women were given the pill in a single day on Sunday.
Health Secretary Ismael Sueno said the new surge in pregnancies has come at a critical time.
“This is a time when we need to show strength, because we are facing a crisis,” he said.
He urged the government to provide more information on the pill.
“We are also waiting for the final results of the results of an assessment on the efficacy of the drug to assess whether we are on the right path to prevent a rise in pregnancy,” he added.
The Philippines is among countries where women are denied access to abortion pills because of the country’s restrictive abortion laws.
It is the world’s only country that does not provide abortions, with women often forced to abort unwanted pregnancies to avoid prosecution or jail.
The new drug has been approved for use in the United States, Japan, China, Singapore and the Philippines.
But the World Health Organization says it has no scientific proof that the pill is effective in preventing pregnancy and that there is a risk that it may cause side effects.
The drug is approved in the US under the brand name of Plan B.
In December, President Rodrigo Duterte said the pill would be available in the “next few days” after an earlier plan was shelved due to lack of funding.
The government has already launched a nationwide emergency contraceptive campaign, with a call to end the “123 pill problem” and to make birth control available in every home in the nation.
It has also announced plans to distribute 1,000 free condoms and 1,600 free contraceptive tablets to pregnant women, who are also being offered free contraceptives.
