Menstrual Cycle: Women's menstrual cycles can vary in length for a variety of reasons. Small changes in your cycle does not necessarily mean that something is wrong. Stress, weight changes, breastfeeding, medications and menopause can all contribute to changing cycle lengths. Lab tests done by your physician can tell you if you have an STD. Using a condom during sex can reduce your chances of getting an STD.

Call the clinic: They may have done tests for STD, so go back for a recheck and ask if they did. If symptoms continue, then you should also return for a repeat exam. Discharge doesn't always mean STD, but can. Also ask your partner about any symptoms and encourage him to be evaluated.

The only way to: see if you have an STD is to get tested. A urine sample, or swab of the yellow fluid will make the diagnosis. I recommend a full STD check which includes urine for gonorrhea, chlamydia, and trichomoniasis. An exam to evaluate for warts, lice, herpes, etc and blood tests for syphilis, Hiv, and hepatitis C. This is a very complete list of STD's not to scare you but a good reminder to use condoms
