This may be weird to ask....

So I woke up this morning and I went pee and my pee was slightly yellow but very very cloudy I couldn't see through it. I had sex the night before last night (fertile window), I used to suffer horribly from UTIs but not a single symptom of that and I drank plenty of water yesterday and last night. Anyone know if this could be a pregnancy sign or if something else is wrong. I've been with the same partner for over a year and we've both been tested so it's not an std.
