I thin you need to clarify some parts of your post & be more specific. You had unprotected sex but are on BCP's? You vomited, and he's not "doing so good either"? Meaning he is ill too? Maybe you both have a stomach bug?

You should be using another form of BC while beginning the pills. But as you notice in the leaflet, depending on the type of pill & the day you begin them, they become effective (most) either day 1 or day 7. It's a generalization which the manufacturers put in the literature and some Gyn's use this. Now other Gyn's say go through one full cycle using another form of BC, as Brandye also recommends. If you missed any pills or took other meds while on them it's another story, you need to use back up birth control.

Now if you have just begun the pills, this is your first pack, it takes time for your body to adjust to the pill. When you stop the "active" pills it causes a withdrawl effect which means you begin to bleed at any time there after. Now if you are not used to the pill, it may not happen right away. Why? Many women have a normal period every 28-31 days. Now you go on BCP's and it's only a 21 day cycle, you stop the pill and wait for the bleeding (the onset of your period). Now if you were irregular before the pill, who knows when it may begin. The pills are low dose and it takes time to get used to them.

If you are concerned, call your doc. If you have taken the pill you should not be ovulating so a pregnancy should not happen and a home preg test will not pick up a positive result this soon (you said this was the other day so I assume 2 days ago?). Give it a few days yet. I would not add plan B to this mix either without talking to your doc--so don't ask that one. If you have taken the pills, not missed any, not taken other meds such as antibiotics, and your regular cycle is every 28-31 days, I would hold and stop worrying. If you notice no onse of a period in the next few days call your doc, sometimes they either switch the pill, induce a cycle, or they will tell you when to begin the new pack.

In the absence of diseases, sex does not make people ill. Worrying because he was not 'properly attired' can cause physical reactions that mimic illnesses. Most likely you aren't pregnant but see your doctor to be sure. The hormones in BCPs are powerful enough to work quickly but the exact amounts vary between manufacturers.

If you could go to the trouble of being on BCPs and he couldn't go and get condoms - why are you with him? Please remember: if he doesn't have (condoms), he doesn't get (intercourse). Do not let men escape their responsibilities again. Those males who seek to avoid their fair share aren't men worthy of your time and attention. Next time do not be so accommodating.
