Thanks for the query.
I understand your concern.
If you had unprotected intercourse around the time of ovulation, there is a possibility of pregnancy.
Nausea, abdominal cramps etc symptoms can be seen in other conditions like pelvic inflammatory disease, premenstrual syndrome etc.
So, just by symptoms we cannot come to a conclusion regarding pregnancy.
If she misses her expected date of periods, let her go for urine pregnancy test once.
Hope this helps.
