How likely is ovulation if i missed 2 birth control pills in a row during the second week? (doubled up after missing) my pill has 0.35 mg estrogen..

Possible : That's why you must scrupously take those pills! They are much more effective if you actually use them as directed. You should abstain from any sexual activity for the rest of the month if you want to guarantee that you won't get pregnant this month. Be more careful in the future. We believe skipping one day is safe, two days is risky.
