Weird possible pregnant symptom...

Wh

Okay when I was pregnant with my son the first thing I noticed that was odd was I couldn't empty my bladder like I would have to move a reposition to get all the pee out. At the time thought it was a uti then found out no uti but was pregnant. I have had the same feeling all day and did a uti test strip completely negative. I am 8dpo so I know a pregnancy test won't show me anything.

Am I just crazy??
