Go to a doctor for better assessment. Baka need ka na i-transv to check your uterus. Or too early for your PT and serum test. You usually have to test on the last day of your next menstruation. So if April 27 let’s say May 27 ka dapat magkaroon, depending on how many days mens mo for example 4 days so dapat by June 1 solid lines na yung PT and positive na ang serum test. This is assuming regular menstruation mo and generally healthy ovaries.
