How it works
We add 13 weeks (91 days) to your last injection date. The WHO Family Planning Handbook says a repeat injection can be given up to 4 weeks late without needing extra protection.[src] If you are past that, talk to your provider before your next shot and use condoms meanwhile.
DMPA product costs from ₱99 a dose (product only), or ₱300 to ₱900 at private clinics, and it is free at barangay health centers, subject to supply.[src] Read the full injectable guide.
