I am not sure whether it would mess your results on a OPK but I would be concerned with your pregnancy should you become pregnant and having a UTI. Are you being treated for the infection? Reason being, I recently m/c 4 weeks ago and I was having some irritation and of course frequent urination (as I was pregnant) and am now having a second urinalysis done to see if I have an infection. My healthcare provider says that if I do have an infection (and I did, in fact, have one while pregnant) that could've caused my m/c. Make sure you get treated. You just don't want a possible factor interfering with the health of your pregnancy should you become pregnant this cycle. Good luck!
