paranoia :(

we were fucking around he pulled out his dick, i licked his pre cum and im really not sure if he fingered me after that. or we stopped. that was 2 days before ovulation. and then three days after my fertile period (5 days after ovulation) he came on his right hand, he swore he didnt have any cum on his left, and then fingered me with the left. if he used the left hand, he used it to wipe. he then fingered me. should i worry about pregnancy :(
