Hello Doctor, I'm 19 years old. My last period started on 27 May, and I still haven't gotten my periods. My periods have always been irregular. I'm really worried because in June I had genital rubbing with my partner, but there was no penetration. The penis did not go inside the vagina. I noticed some white fluid, but it was on my pubic hair, not near the vaginal opening. For the past few months I've also had: Increased facial and body hair growth Acne Significant hair fall Could this be due to PCOS or another hormonal issue? Based on what I've described, how likely is pregnancy, and what should I do next? I'm very anxious and would really appreciate your guidance.
