Tulana is a good pill option if you are breastfeeding, have migraines with aura or neurologic side effects, high blood pressure, heart attack history, or are smokers and over 35 years old. Birth control pills are 99.7% effective if PERFECTLY used (in a research study) and 93% effective in “regular use” (when real people use it and mess up every now and then). However, with these pills, if you are 3 hours late, then you will need emergency contraception (if you had sex in the past 5 days) and to abstain or use backup for 5 days.
