Hi madam, sorry this reply is coming this late, really sorry for that.
Unfortunately, I do not know of any drugs to prevent semen from flowing back from you private part after intercourse. like I already said, there really isn't anything like that as far as inability to achieve pregnancy is concern.
Instead of spending extra money and time on things that will not help you in achieving pregnancy, kindly make the effort to see a gynaecologist and receive the appropriate care ASAP.
