Plan B I took it after having unprotected sex 4 days later is it to late?

It sounds to me like side effects of Plan b. Plan b is just a huge dose of hormones. It can really mess your cycle up for a few months. It is best to take within the first 72 hours of a contraceptive failure. Plan b is not meant to be a birth control pill. Also I want to warn you that a male pulling out before ejacualtion does little to nothing to protect against pregnancy. A man secretes sperm all through the whole sex act and it only takes one! Studies have shown that Plan b works best when taken in the first 72 hours of a sexual encounter but it can work up to 5 days after so you are probalby ok. Plan b doesnt always work however. If you were impregnanted before you took it, it will not terminate a pregnancy. It wont hurt a fetus though if you happen to be already pregnant when you take it. Plan b can cause bloating, sore breasts, acne, increased appetite, nausea, etc so it can mimic a lot of the pregnancy signs. I'm not a big fan of Plan b.

I think it allows people to think they can go ahead and have unprotected sex and gives a false sense of security and too many girls try to use it like birth control. Once you take Plan b you return to fertility quickly so dont fall into thinking you are protected for a few days when you take it. In this day and age birth control is very easy to come by and there is really no excuse for unprotected sex. Condoms and foam are available at any pharmacy/drug store/Walmart/most grocery stores and condoms are even in many public bathrooms!! If you are adult enough to have sex, you should be adult enough to protect yourself. If you miss next months period, go ahead and take a pregnancy test. If it is negative then you are not pregnant.
