She missed 2 pills last cycle, one at the beginning, one near the end, first by 14 hours, then by 16. She took the missed pill when she remembered then continued regularly. Got her period regularly. Now, 2 days into this cycle I ejaculted inside her and left it sit all night without letting all of it drain. (7 hours) We are only slightly worried because of the missed pills, though they weren't missed by much and not in a row. Does the length of time that the bulk of the sperm stayed inside her have much affect? And do we have anything to worry about/should we consider plan B? It is currently 18 hours after the incident.
We have a page on this site that advises how Mononessa missed pills should be handled:
'If you miss one active pill, take two pills on the day that you remember. Then take one pill per day for the rest of the pack.
If you miss two active pills in a row in Week 1 or 2, take two pills per day for two days in a row. Then take one pill per day for the rest of the pack. Use back-up birth control for at least 7 days following the missed pills.
If you miss two active pills in a row in Week 3, throw out the rest of the pack and start a new pack the same day if you are a Day 1 starter. If you are a Sunday starter, keep taking a pill every day until Sunday. On Sunday, throw out the rest of the pack and start a new pack that day.
If you miss three active pills in a row in Week 1, 2, or 3, throw out the rest of the pack and start a new pack on the same day if you are a Day 1 starter. If you are a Sunday starter, keep taking a pill every day until Sunday. On Sunday, throw out the rest of the pack and start a new pack that day.
If you miss two or more pills, you may not have a period during the month. If you miss a period for two months in a row, call your doctor because you might be pregnant.
If you miss a reminder pill, throw it away and keep taking one reminder pill per day until the pack is empty. You do not need back-up birth control if you miss a reminder pill.'
If you feel you want extra protection against pregnancy in this situation, then Plan B is only effective for up to 3 days (72 hrs) after the unprotected sex, so your GF would need to ask for the EllaOne tablet, or have a coil/IUD fitted. Both of these can be effective if used within 5 days of the unprotected sex.
