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.
