Cause of clear vaginal discharge with tcp type aroma?

I do not know what TCP is and it’s aroma, however odorless clear vaginal discharge typically occurs just before ovulation. Consider using a menstrual calendar to see if it correlates. Also, consider discussing with your Obgyn for further evaluation. Bad odors typically indicates a vaginal infection like bacterial vaginosis and only way to determine that is by seeing an Obgyn. I hope this helps.
