A single episode of delayed cycle and blood tests do not suggest PCOD
. The diagnosis of the condition is made based on several factors like the menstrual history, physical appearance, hormone profile, sonogram of the pelvis, other tests like DHEAS levels, insulin resistance
etc. Though every typical feature may not be present in all cases, majority are seen most of the times. Please see a specialist for a proper evaluation and plan further management. Nausea
can happen due to several causes and you should exclude pregnancy
through a blood test; hyper-estrogenic states also can cause nausea. Hope this helps.
