Thanks for the query.
Just by symptoms we cannot confirm or rule out pregnancy
, most of these symptoms can be seen in other conditions also like premenstrual phase etc.
So you once consult gynecologist get examined, go for one ultrasound
to find out the possible cause for your delayed periods.
Meanwhile you can take symptomatic treatment. Take support of your family members in overcoming the depression
