Hi, Welcome to HealthcareMagic Forum.
If you have had Unprotected sex, around the 14th day of her cycle, then there could be chances of Pregnancy
. Wait for her next periods, if she happens to miss it, you should be getting a Urine Pregnancy test done using a early morning urine sample one week after missing it as it is the most ideal time and to avoid false negative results. If it comes out positive then, she should be examined by a Gynecologist for further evaluation. Until examined, nothing can be prescribed.
Good Luck to you both. Take Care.
