Hi, I have a serious question I was masturbating myself with my hand and the pre-cum was all over my hand, then,i started fingering my girl for some time. After that, I thought this scene would cause pregnancy. So I gave a pill of (levonorgestrel usp 150 mcg, ethinyl estradiol usp 30 mcg) in the 72 hours and she took 3 pills in the next three days at the time interval of 24 hours. So,after a very month, she started bleeding, but she only bled for like one and a half day only, whereas periods are of 6 days, so can you please tell me, if there is anything to worry about?
