I wish I could answer the question if you are pregnant or if you are not. However, it is impossible for us to diagnose you over the internet.

From the info you gave there is no way even a doctor can tell you if you are pregnant or not.

Have you missed a period? How late is it? Have you taken a HPT yet? If not, and you are late, it would be best for you to take a HPT using first morning urine.

A pregnancy test, either HPT or blood test at your doctor's office is the only way you will get your answer.

Also, remember that you have only been trying for 4 months. It takes many healthy couples a year or more of actively trying before actually conceiving.
