On the 24th of this month (October), I did something incredibly stupid: my boyfriend and I decided to fool around without any protection. Although we DID NOT have traditional vaginal intercourse (penis in vagina), we did rub our genitals together. Meaning, the tip of his penis was around/touching/facing my vulva or vaginal opening. I am concerned because I know he had pre-cum on the tip of his penis and, for the life of me, I cannot remember if we wiped it off.

 During that time, I believe I tried to insert a finger into my vagina as well but I cannot remember if I had pre-cum on my finger. If I did insert a finger in myself, it would not have been very far inside because (1) I am a virgin and (2) I was not very wet. He also accidentally ejaculated on me, but it was towards my lower abdomen and the beginning part of my vagina--where the clitoris is located. As soon as I saw this, I wiped it off immediately and attempted to wash my vagina with some water and a tissue. 

The next day, I went to the store and bought Plan B and took it at approx. 1:10 pm. We had our "intercourse" around 4 or 5 pm. the day before, so I figured that was a reasonable amount of time for the contraceptive to work and help avoid an unwanted pregnancy. HOWEVER, I looked at my period tracker and it says that I was ovulating when I took the pill. My last period was around the 11th of October. I am not 100% sure of the exact date but I know it was on or around that time. If I was ovulating what does this mean? Will my chances of becoming pregnant be higher? Did the pill not work? 

Additional Info. : It is now the 28th of October, so this happened four days ago. I am 18 years old, if that helps. I'm only 98 pounds... I have noticed that my vaginal discharge looks kind of like a white blob. It's not long, rather scant; it kind of looks like a miniature cotton swob! It is kind of mushy, and holds its shape.Anything you can offer to this matter would be greatly appreciated. Thank-you for your time and patience. If you need any additional details, I will be more than happy to answer as accurately as possible.
