STOP taking the pill and see a health worker if you:
have severe headaches with blurred vision (migraines) that begin after you start taking the pill.
feel weakness or numbness in your arms or legs.
feel severe pain in your chest and shortness of breath.
have severe pain in one leg.
have severe pain in the abdomen.
If you have any of these problems, pregnancy can also be dangerous, so use another type of family planning such as condoms until you can see a health worker trained in hormonal family planning methods.
