Hi Trisha


Does it burn when you urinate?  Are you having any pain? 


Did your partner have anal intercourse with you and then vaginal sex?  That scenario could place you at risk for an infection.


I am not a doctor so I cannot tell you why you are having these symptoms.  But it does seem that it could be a possibilty that you have some sort of infection.  Dark could just mean it is more concentrated and that you need to drink more fluids...that may also explain the odor. 


But why don't you make an appointment with your gynecologist just to make sure.  You don't want to have a urinary tract infection or something like that and go untreated.


Thank you for your question.

First, make sure vaginal NEVER follows Anal without extensive cleansing of the partner. I am a gay man that recently noticed a fishy odor from my partner during anal intercourse. I researched and found that this was linked to his IBS which he has had for years. I started him on Align probiotic. It is a fairly new over the counter digestive pill that restores healthy bacteria in his system. This should work systemically (vaginal and intestinal) to some degree. In 1 week the difference is amazing! I highly recommend you try it.
