Had unprotectrd sex early Wednesday morning about 1am and didnt take plan B until Wednesday night about 8pm. And my period calendar say I ovalute that Thursday. Then Friday morning I had sex about 1am, 7am, and 4pm but at 4pm we had unprotected sex. I'm not sure if I will or wouldn't get pregnant.
The way that Plan B works, is by delaying ovulation. If it is too late to do that, then you may become pregnant. If it can delay ovulation, then it is said to be around 90% effective if taken within 12 hours of the unprotected sex. It gradually becomes less effective until the last point it can be taken (72 hours/3 days) when it is around 75%.
It is thought it might work in other ways, but the Manufacturer is unable to guarantee those as they are not proven.
The Manufacturer states that Plan B does not cover you for any other episodes of unprotected sex, once you have taken the drug.
You are not meant to take more than one dose of Plan B in any one cycle. It is a huge dose of hormone to take once, & there are no studies done on the side effects of an overdose.
Women who have taken it twice in the same month, report significantly worse side effects. Plan B is known to cause many women lots of hormonal side effects for some time after using it, but to take an overdose could leave you with things like very heavy bleeding in the first place, then spotting (brown/pink/red), irregularity or no periods for months. The cramping could well be very significant, as could symptoms such as nausea, fatigue, mood swings/depression & others. The long term side effects are not known if overdosing.
It is therefore up to you as to whether you take a further dose.
The other option you have, is to have a Coil/IUD fitted within 5 days/120 hours of unprotected sex. This can act as emergency protection, & can also be left in place for longer term contraception. A doctor or family planning clinic can do this for you.
