UTI after ovulation driving me crazy

Rosalind • Trying not to stress about starting a family in my 30s.
So my husband is deployed a lot or on assignment somewhere other than where I am. So when he comes home I am a stickler for tracking everything and utilizing everyday of the fertile window. Now I am having some lower back pain and painful urination. I recently visited my obgyn so I know there's nothing seriously wrong but I feel like it's a UTI because this isn't my first rodeo. Has this been an issue for anyone else?
