I had unprotected sex on 27th pf january , after coitus she took the birth control pill not the emergency one but the regular one, she has been taking one daily and has taken 4 till now but i still fear the risk so should i make her take the emergency one as well as the 72 hour window lapses soon. Her last period cycle was from 16th 19th January. The pill she took contained levonorgestrel 0.15 mg Ethinyl estradiol 0.03 mg.
