Can taking emergency pills for three consecutive weekends make your period miss or late.help please

Yes but why do that: Anyone having intercourse without birth control or condoms may get pregnant. If intercourse was within 72 hours you consider taking plan b. Plan b is a high dose of birth control to disrupt the hormonal patterns to delay or prevent ovulation. Abnormal bleeding after is common. Check preg test in 10 days. Clearly you need a better birth control plan. Buy condoms. Avoid unplanned pregnancy.

Yes: It can certainly turn your menstrual cycle upside down. You need to be using a regular form of birth control, not relying on emergency contraception. If your period is seven or more days late would take a home pregnancy test.
