Hello Good Evening,
Pre-ejaculate or pre-cum is the clear, colorless, viscous fluid that emits from the
urethra of the human penis during sexual arousal.
It is similar in composition to semen but has some significant chemical differences. The fluid has found no or low levels of sperm.
Pre-cum is believed to function as a lubricant and an acid neutralizer. The amount of pre-cum emitted varies widely between individuals; some men emit none.
The vagina is normally acidic, so the deposit of pre-cum before the emission of semen may change the vaginal environment to promote sperm survival.
But in your case pre-cum rubbed only around the
vulva, not inside the vagina, so very rare chances to get pregnant even if she were in fertile period, so be relaxed and wait for period to come.
Rather than if you wish for her to take
emergency contraceptive pill, such as I-pill then proceed, nothing will affect her future pregnancies or her ovaries, but do not think for i-pill frequently in future, because they can cause
hormonal imbalance, to be used as an emergency, not as regular or frequently.
