UTI Symptoms: A sign??

Alicia
I'm 8-9 dpo as  yesterday and today I've had off and on UTI symptoms. They are not severe - very mild. Just once or twice I've felt like I had to pee and just a little came out and there's slight burning. 
I haven't had a UTI in probably 10 years and I'm a clean person who hasn't had sex in 3-4 days. It seems that it's coming on randomly and I'm wondering if anyone has noticed this as an early pregnancy sign. 
I've been trying for my rainbow baby since April and hope this is my month!
