my boyfriend ejaculated on his hand and washed it with water only and not soap. he then fingered me after 15 mins when his hand was completely dry. as he didnt wash his hand with soap we took an emergency contraceptive pill. i had felt nausea, cramps and headaches in the first 3 days. then felt nothing for another 2. and now on the 6th day again i felt nauseated, headaches and stomach aches. i need to be worried? we didnt have sex. and im still a virgin.
