Three months without a period, is it pregnancy?

Patient's question:

Three months without a period, not pregnant, belly getting bigger

Doctor's answer:

Hello: Generally speaking, if you have had sexual activity before and now your period is delayed for three months, it could be pregnancy, or it could be irregular menstruation.
Advice: It is best for you to go to the hospital to check your blood HCG to confirm if you are pregnant. If you are not pregnant, you should also check for inflammation or other diseases. The occurrence of irregular menstruation not only affects a woman's body but can also lead to gynecological diseases. Therefore, it is best to go to the gynecology department of the hospital for a routine check-up, identify the cause, and then receive targeted treatment. Also, pay attention to personal hygiene and keep the vulvar area clean.
