Not sure what is happening.

Okay so all day i haven’t had any symptoms of a UTI. not at all. i’ve had a few before but i remember when i would get them i would be feeling like crap all day long. but not today. but when i went to the bathroom just now it burned right after i peed and then it stopped. usually when i have a uti it burns all the time no matter what until it goes away. i’m just confused as to what it might be? also is it normal since i’m almost 5 weeks pregnant. tia.
