Please give your valuable opinion. Problem: July month period on 13th June was light (First day normal, second and third day light), immediately checked for urine pregnancy test, Its negative check on 20th and 21st june. August month period supposed to come on 13 july didn't come yet, waiting for period, checked urine pregnancy test, its negative. Checked on 10th august its negative, checked on 25th august same urine test its negative. NO symptoms of vomiting, nausea, headache, no frequent urine, no tender breast, no morning sickness. I was stressed in june july, not sure if it has the effect. Any solution?
