Pee stinging and reddish😬

So today my pee has been stinging all day and has a little red to it and have been needing to pee a lot more but just a little comes out. I’m freakin out because I have no idea what’s going on and keep reading I might have a UTI. I don’t know what to do and also I’m freakin out because normally I pee after sex every time and it always stings a little but nothing to bad and then it’s done but now I don’t know if that normal😬please someone help I have bad anxiety and I’m really just freakin myself out more😬
