Hi Juliaho90, there is no risk associated with what you describe as the timing of sex doesn't have any effects on the effectiveness of your hormonal birth control. What does effect it is the dose interval of taking your pills, which as you note was maintained correctly.
This is because what the combination pill does in your body is effect the ways that your anatomy would try to work to be able to conceive a pregnancy in three ways: it prevents ovulation, to thicken cervical mucus so sperm cells are less able to get to or into the cervix, and by making the lining of the uterus less hospitable for a fertilized egg to implant in. Maintaining the dosages of the synthetic hormone in your body as per the manufacturer's instructions is the important thing, and engaging in sex, unprotected or protected, does not change this, only maintaining the required consistent frequency does.
Furthermore, even if you had completely missed the pill, you engaged in protected sex, which means that the chance of pregnancy would have been very low, as it sounds like it didn't break, you remembered to use it, and followed the instructions on how to use it (forgetting to use a condom or occasionally using it incorrectly are what account for the stat of condoms being 86% effective across one year of typical use - this means that for sexual partners who use a condom as a form of birth control for a whole year, that in that typical year they will use it incorrectly or forget it, and then of all people using the condom in a typical manner (sometimes getting it a bit wrong), then 14/100 people would get pregnant, so in other words, even using it imperfectly
, 86/100 people will still not get pregnant).
I bring this up in part because I've noticed you have a tendency to second guess the effectiveness and become highly concerned risk profile of situations in which you are using one of the most highly effective combinations of birth control available, 99.99% effective with perfect use, 98.7% effective with typical use
It sounds like even that tiny chance causes you a decent amount of stress, so that you get concerned about fringe cases that don't have an impact on the effectiveness on the methods you have chosen. There appears to be a pattern arising where you get concerned about this, seek reassurance from us but then because this relief isn't actually addressing the underlying lack of confidence you have that you are using the method correctly, or that you can trust it, the cycle then repeats at the same trigger. We are of course happy to help, however this sounds like a very stressful situation to be in and that by us not addressing the root of the issue with you, that we are only feeding into this anxiety cycle, which means in a way, we are not helping resolve your concern. Is this something you would be comfortable looking at with us?
In the immediate term, you might find it useful to re-read our articles on the combined pill
to really solidify your understanding of how they work.
Following on from that, would you be open to discussing this a bit further? We could discuss what you'd need to trust your use of birth control, or if there is a particular fear you have about being able to end an unwanted pregnancy in the event that the very very low chance that you became pregnant? Or, discussing whether you'd like to look at a form of birth control like an IUD which is 99+% effective in one year of perfect or typical use
; because there is no real element for user error in order to assuage your anxiety about using it incorrectly? It is okay if you'd prefer not to discuss some or any of these things, and I hope it is not too confronting for me to be asking, I just think that it may be more helpful to look at all or any of these points to assist you with these concerns in a more long term way.
