I'm 21 and have been experiencing bleeding and mild cramping between periods. It lasts for days at a time, is a dark rusty red in colour with occasional small blood clots, and is not consistent with a certain time in my cycle (e.g. sometimes occurs days before ovulation, sometimes after). It is heavier than the light, brown spotting I have experienced between periods in the past, but not as heavy as a period. An ultrasound and a blood test showed no worrying results, I am not pregnant or on the pill, and the gynecologist I visited dismissed it as stress (I have in recent months moved to a new country with a different language). However, I feel that he did not take my concerns seriously, especially coupled with the fact that I have had difficulties with pain during sex also. Do you think it is worth getting a second opinion or should I just dismiss my concerns altogether given that the ultrasound was clear?
