Hi. I am 29 and almost 20 days late .my lmp was 5th feb but am usually late by 2 weeks. yesterday I took upt which was negative but after 5 min a very faint line appeared. Last night I had cramping pain in right umbilical. Today usg showed no sac or tubal pregnancy. Only 3*3.5 cm simple ovary cyst in right side. What should I do? How to get my periods ?do I again check with usg if its very early pregnancy.
