Thanks for the query.
I understand your concern.
Spotting from vagina may not be due to sleeping in the prone position. Intermenstrual spotting can be seen due to causes like hormonal imbalance, side effects of the hormonal contraceptive methods, pelvic inflammatory disease presenting with cervical erosion, cervical polyp, post-coital bleeding, in case of pregnancy implantation bleeding etc.
If the spotting persists or repeats better to consult Gynecologist once and get examined.
By an examination and ultrasound, the possibility of pregnancy or any other possible cause of spotting can be identified and management can be planned according to the cause of your problem.
Hope this helps.
