Pcos issue or pregnancy? Pregnancy?

Hello doctor, I am 18 years old. My last period started on Jan 15 Feb i dont remember shayad nhi aaya tha uske baad  23rd March. I have PCOS, so my periods are usually irregular, but this time I'm worried. Around 20th April, I had an intimate moment with my partner — just outer rubbing, no penetration, and no ejaculation inside. But I’m still anxious. Since then, I’ve been experiencing bloating, light lower belly pain (dull), and white discharge (sometimes watery or sticky). No bleeding, no vomiting, no breast tenderness. I haven't taken any emergency contraceptive and I'm under a lot of stress. Could this delay be just due to PCOS and stress? Or should I be concerned about pregnancy? i asked a doctor she said there is no pregnnacy risk but i am stressed and confused Please help. I'm very worried.
