she is not pregnant....as yu didnt ejaculate in her vagina...so enjoy
You both having nothing to worry about.
Getting semen on the panties would not get someone pregnant. It is possible to get pregnant when there is penetration even without a full climax on the man's part. This is because there is some seminal fluid released even before a man ejaculates.
The early bleeding was due to taking the emergency contraception medication. Tell your girl friend to keep a written record of her menstrual cycles and these will return to a correct pattern when things have settled down.
Neither of you should worry.
If you are both ready to enjoy the intimate pleasures of sex and want to have penetrative sex, then I suggest you use latex free condoms and a good water based lubricant. Some people have an allergy to latex. Always wash your hands after using the toilet and before touch your girlfriend's body.
She can't get pregnant through clothing and the emergency contraception was completely unnecessary.
sometimes contraceptive pills can cause bleeding. they say so right in the side effects as well as sometimes emergency contraception can change the length of a monthly menstrual cycle, making the next period come as much as a week earlier or a week later than usual. if her period was late than you should worry but any bleeding heavier than spotting is a sure sign that she is not pregnant.
