<s>[INST] hello, im jem. 21 yrs old. I have an unsafe sex with my boyfriend 4 days ago without ejaculation, then he had ejaculated last 3 & 2 days.Last night I took one pill (Lady oral  contraceptive pill manufactured by Ponds Chemical Thailand R.O.P.) and this morning another pill. Would this be effective to prevent pregnancy? Will I be harmed taking this pill im using? [/INST] Lady oral contraceptive pill are regular contraceptive pills. They have to be started ideally from second day of the menses and taken throughout the menses regularly. Random consumption of these pills does not give you protection against pregnancy. To use them as post-coital contraception pill, the dose would be much higher, which you have not taken. Now the best option for you is to wait for your menses. If you do not get them, then wait for further 8-10 days to get urine pregnancy test and/or ultrasonography to detect the pregnancy. These tests done earlier may not give reliable results. Beta-ChatDoctor tests are highly specific and sensitive. Their results are reliable even 2-3 days after missed period. If you are pregnant, and you do not want pregnancy, you may terminate your pregnancy by medicines also. They terminate pregnancy safely up to 9 weeks of gestation. Please remember these medicines have to be taken by Obstetricians advice and under his/her observation lest the risk of incomplete abortion and/or infection. Please do not take these medicines over the counter. I hope I have guided you fully. </s>
