Hello Thanks for your query. I will try my best to provide you with best possible professional recommendations to your questions. If you are speaking about pre ejaculate, Technically speaking pre-ejaculate does NOT actually contain sperm in and of itself but can pick up leftover sperm from the man s urethra from previous ejaculations. The chances are EXTREMELY LOW low that a woman gets pregnant from pre-ejaculate. But, this does not mean there is NO chance a woman can get pregnant from pre-ejaculate. Before taking any pills you to conform whether you are pregnant or not. If you have missed period then you can do urine pregnancy test, using kit which are available in market. Instruction and interpretation is provided with kit. I advice you to perform the test with early morning urine as the accuracy is increased using this sample. If she is pregnant i advice you to see OBG specialist and then consume the drug under their supervision. Possible side effects of i pill include nausea, vomiting, stomach pain, dizziness, breast tenderness, tiredness and weakness, headache, menstrual changes, and diarrhea. Yet again, I do hope that you have found something helpful and I will be glad to answer any further query. Regards
