2 days ago my menstrual cycle started like a pinkish brownish color like little stains and then it stopped. started again pink color and stopped again?

Your ?: If you've had sexual intercourse in the month prior to this odd menstrual period, I recommend a home pregnancy test regardless of whether you're using contraception If it's negative, I personally would wait at least another cycle to see if your cycle normalizes on its own. If it doesn't, contact the doctor who provides your gyn care. Best wishes.
