If you have not had any intercourse in the recent past, chances of pregnancy
are rare. At your age, hormonal
imbalances are common and this could be the reason for the irregular discharges seen. Maintenance of a healthy weight, regular exercises and avoidance of stress
through relaxation techniques
help a lot to maintain the hormonal balance. Yet, you need proper evaluation by a specialist to look for the exact cause and plan further management accordingly. Hope you find this information useful. Take care.
