Hi,
Thanks for posting in HCM.
The chances of you getting pregnant depends on having unprotected sex during your fertile period, especially between day 10 to day 20 counted from the 1st day of your menstrual period.
There is a chance for
pregnancy with penetrative sex, even if he has not ejaculated inside you and pulled out his penis, as
pre-ejaculate fluid contains sperms which are capable of fertilization.
Now, since you have not taken any measures of
contraception, you need to wait till you get your next periods. If you get it, then it says you are safe and you are not pregnant.
In case there is a delay or you miss the period, get your urine tested for pregnancy. If it comes positive, then it indicates that you are pregnant.
Hope the information provided is useful for you. All the best.
