From when should I take a pregnancy test, as I cannot rely on my menstruation? Should I do ovulation tests?

It is recommended to wait 4 to 6 weeks after trying to conceive before taking a pregnancy test, especially if menstrual cycles are irregular. It is also suggested to have regular sexual intercourse every 2 to 3 days. Testing for ovulation may not be necessary, as it is more important to know the duration of the menstrual cycle in order to use them effectively.
