Hello, I'm jhane.. I have menstruation last December 16, I'm delayed until now, omg.. What happen to me, but I go to clinic for check up, the pregnancy test is negative and no signs for pregnancy, do I need a ultrasound? But I want to know first, if you have information about that case before? I really want to know

Information about what case? We only know what you tell us.

You said you were late for your period until now. Does that mean that you have had your period since December?

You went to the doctor for a pregnancy test and it came back negative. If you are still concerned you should go back to your doctor.
