Mashimaro,
That is great that you took so much time to research, and looked in very credible and reliable places for the information!
Also great that you took your missed pills as directed the following day with that same-day's pills. Bravo again!
You have not been able to find any exact information on your chances of pregnancy, because it is not an exact science. It all "depends" on many factors, and those that relate specifically to you include:
- Taking the pill consistently and correctly every day results in 99% effectiveness from pregnancy
- Taking the pill any less than perfect use results in a decrease in effectiveness. There is no statistic for exactly how much decrease.
- The withdrawal method has a 75-90% effectiveness rate when used alone, depending on typical or perfect use.
- You stated confidence with the withdrawal method, and if he did not ejaculate inside/near/on your vagina, this would be an added protection (guessing around the higher effectiveness-range).
If he knows 100% that he did not ejaculate, you would have no chance of pregnancy. There is some discussion that pre-ejaculatory fluid (the few drops on a man's penis when it becomes erect) may contain sperm, but most sources say it does not without the man ejaculating beforehand, at an earlier time and not wiping the semen off. I am not sure of any instances where a woman became pregnant from only pre-cum and no ejaculation.
With these odds, you are in pretty good shape for being protected from pregnancy. The only way you could have increased your odds were to: use a condom on Thursday (since you knew you missed Tuesday's pill), use emergency contraception after Thursday's unprotected sex. Those are just options in the future, as it is wise to plan for the "oops" in life...women can forget to take one pill, may go on vacation, may be sick and not take it...life's circumstances may result in the possibility of missing a pill in the future, and it's good to plan ahead.
One other statistic for you: women "only" have a 20% chance of pregnancy every cycle, even while actively trying (off birth control and having frequent, unprotected sex with ejaculation). Of course, it only takes that one time...but it is actually difficult to become pregnant with timing, ovulation, etc.
It is great that you did not have many hours without (synthetic) hormones, but please know anytime you miss more than one pill, the effectiveness rate does decline. This rate declines rapidly with additional missed pills (3 or more), it declines rapidly with missed pills on consecutive days, or when the pills are not taken as soon as remembered.
