Hi there, I have understood your concern. I will suggest you the best possible treatment options.
1 ) First of all do not panic.
2 ) It is the first sign of
pregnancy that a woman misses her periods.
If you are having your periods regularly, you are mostly not pregnant.
Still if you have any doubts, blood
beta HCG test and USG will be of help.
3 ) It won't be wrong on my side to suggest you to get proper sex
counselling done.
You must be aware that whenever there is penetrative sex, in absence of ejaculation there is possibility of spillage of sperms from pre ejaculation secretions.
It is advisable to use barrier
contraceptive method like condom, this will help to prevent unwanted pregnancy a d
STD.
I hope this answer helps you ..
Thanks.
