Serious Only Please-Unexplained discharge-ovulation?

I have a complex issue. I am 35-completely middle-of-the-road cycle - every 28 days give or bring. My birth control is IUD - one partner - seemingly around my time of ovulation, I have a slight discharge that have a tinge to it. Also, cramping - this only last a couple of days. Just got a regular pap test and talk to Dr. about it - he took another swab for infection but nil on that either. I didn't regard it was that because it isn't at hand every day. Any thoughts would be appreciated. if it is foul smelling ,most probable it may still be an infection, false negative results is more adjectives than false positive in screening procedures. Get another one lately to be sure and have your self ruled out for chlamydia which usually yield no result in assessment unless specifically for it. If still negative later it most like due to your IUD, since IUD in actual fact is suppose to cause contractions to work and act as a foreign body thus may cause some inflammatory hostile response and discharge. IUD works by expelling any fertilised ovum from implantation to your uterus by causing contraction and enhance foreign body impulse involving the fertilized ovum in the process. This information process also help build your own decisions that unknowingly to you may affect your own beliefs.
lol I a moment ago answered this question. The small discharge you procure normally occur with ovulation. It's fine...
