First Post-T Doctor's Appointment

Today was my first appointment with Dr. G since beginning testosterone. I reported changes which basically boiled down to genital growth, extremely high sex drive, and the power fluctuations previously mentioned. I brought up the issue of spotting and she is sending me for a pelvic ultrasound. Normally, I wouldn't think anything of this but because of family history of ovarian cancer, Dr. G wants to play it safe. I am curious in finding out how I could be spotting after having an endometrial ablation in 2004. We decided to keep my dose the same for now (100mg/ml every 2 weeks).
