Short Period When Should I Test When Should I Take A Pregnancy Test If My Period Still Came?

When should I take a pregnancy test if my period still came? - short period when should i test

On 8 July came my period. It was 4 or 9 days after I had sex. What worries me is that my time was much shorter and much clearer on the second day.
