My boyfriend and I were fooling around on December 16th. I performed oral sex and he did ejaculate and urineated immediately after. About an hour later he did enter his penis into my vagina with out a condom but just for a few seconds. He did not ejaculate alothough i am worried about him pre-ejaculated inside of me. A while later I felt his pre-ejaculate on my leg so I am assuming men can pre-ejaculate multiple times? On the 19th (less than 72 hours) we decided I should take plan b just to be cautious. I have been experiencing white discharge heavily in my underwear since it is now almost time for me to ovulate. Yesterday (25th) I was alarmed when I felt a rush(as if it was period) but when I went to the bathroom and wiped it was mucus like discharge that was brown. I was bleeding all day yesterday with severe cramps, I woke up this morning and had dark blood all over my pajamas and underwear. I literally bled through everything. I just got off of my period on the 6th so could this be a period or implantion bleeding? I have also been bleeding today (26th) and it is red and some brown but pretty vibrant red with slight clothing.
PLEASE HELP ASAP
