plan b emergency contraceptive

I am starting to get worried, 5 days ago I had unprotected sex with my boyfriend, and I had just stopped taking my regular birth control (triphasil) 2 days prior.  he thought that he may have came a little bit in me, but wasn't sure, so I went and got the Plan B emergency contraceptive for the first time, just to be sure.  I took the first pill about 3-4 hours after sex, and they say it should be within 72 hours.  It has been 5 days now, and i still haven't got my period.  Is this okay?  Could the fact that I just finished taking my regular birth control two days prior make me more susceptible to becoming pregnant??  I am getting really anxious.. I am in the middle of a course that i moved far away to take and this really isn't a good time for this kind of responsibility, since i have 8 months left.. should i be so concerned????

When is your period due?

to my knowlege, plan B is pretty effective.  Did you finish the cycle of pill you were on before you stopped taking them?  sometimes cycles get messed up for awhile after stopping the pill.  It's not uncommon for it to take 3 months (average) for a woman's cycle to return to normal after stopping the pill.  So, don't freak out yet.  Wait a few more weeks and if you don't get your period, take a pregnancy test.

Socgirl is right. The chances of you being pregnant are *extremely* slim.

I'm curious, though; why did you quit taking the pill?

if you want to continue taking the pill, just start a new pack after your period and you should be back on track!! you are not the only one to have done this, I did too and it took 2 cycles of pills before everything felt back to normal. sometimes our worries get a little carried away and we overprotect ourselves.

well I definately feel a lot better after all your comments!  I guess I should clarify that I was at the end of my triphasil package (21) and so normally I don't take them for the 5 days I have my period.  So I was expecting my period the day after we had sex and I took the emergency contraception.  I know that after my last pill of the month it usually takes about 3 days before I get my period, and i thought it might be the same for plan b, but maybe  you're right and it would take longer since it probably did mess around with my cycle a bit.  I have never looked forward to my period so much before!

Oh... well, you didn't need plan b then. The pill prevents you from ovulating, which means you're protected all month long--including during your placebo week. So you probably really did throw your cycle wayyyyy off...

That's why Plan B was created.  For emergencies, such as your case.  It's highly effective.  The fact that you stopped taking the pill and you used Plan B is enough to mess up your cycle for a while.  Alone, emergency contraception will either delay your period a week or start it early.  It's not too surprising you haven't gotten a period yet.  Dont freak, you took responsible measures after realizing he may have came in you.  The chance you are pregnant is close to 0.  Good luck!

But to be safe perhaps you should use another form of birth control as backup for the next cycle!
