<s>[INST] My period was on the 18 of November. I had sex on the 29 of november I took postinor plan b pill the next day. On the 1st of december I had sex again an took the pill the following morning. On December 10 it happen again an I repeated took the pill again. What are the implication of taking the pill three times in a row an could I be pregnant. [/INST] Hello misunderstand your concerned have used plan B pill in the wrong way. It should not be used for regular contraception. If you took pill with in the 24 hour of sex then chance is only 5 percent. Because it is very effective in preventing the pregnancy in around 95 % cases. But in your case high chance of hormonal imbalance as it contain high dose of progesterone. Sometime period may be delayed by one or two cycle or period may be excessive or earlier. If period will be delayed by the 12-14 days then I advise you to go for Blood Chat Doctor or pregnancy test as to diagnose the pregnancy. If pregnancy will positive then you have to abort the pregnancy by using abortion pill under the advice of gynecologist. But High chance of period irregularity and in this case you have to consul the gynecologist for proper evaluation and treatment. Oral contraceptive can be used for irregular period in hormonal imbalance cause by the plan B pillow in future keep the unwanted 72 as an emergency option only. Hope this may help you Best regards </s>
