We didnt use a condom Wednesday night after I took my pill and my other half ejaculated inside me. Took Thursdays pill, but Im waking up Saturday morning realizing I forgot to take Friday's pill and it's freaking me out. I took it just now will take Saturdays at 8pm this evening (took fridays at 5am). I recall a 72 hour time frame for sperm to be able to live in a woman's body!? The booklet for my birth control pills says if late or miss one day take as soon as rememember even if it means taking 2 pills in one day, doesn't say anything about needing a back up method of birth control though missing 2 days does. I'm hoping it should be fine but can't seem to find any answers for this exact situation.
