how late do you have to be taking your birth control pill for the effectiveness of preventing pregnancy to go down? & how much of a percent goes down after being an hour late?
It depends on the pill. For the mini pills its very important you get them at the same time, no more than half an hour late, because the hormones are out of your body in 24 hrs. With the other ones If its more then an hr, then your protection will drip to about 95%. If you miss it altogether it drops to about 90%
