Althea which contains cyproterone
acetate and ethinyl estradiol
does not work as emergency contraception
. Hormonal contraceptive
pills which contain, levonorgestrel
alone or in combination with ethinyl estradiol can be used as emergency contraception.
So there is a possibility that you may get pregnant from that intercourse.
Since you started contraceptive pills in the in the second week of the cycle, they become effective as contraception after 7 days. You can have sex with your boyfriend while taking pills, after seven days of using pills. But I advise you to defer it until next period. It is important to clarify regarding the possibility of pregnancy as you have not used emergency contraception.
Once you get your period I advise you to discuss with your doctor and start using regular effective contraception like hormonal contraception or get an intrauterine devise fitted.
I also advise you to use barrier method of contraception like condom in addition, to protect yourself from STDs.
