Pregnancy symptoms? UTI?

Hello! I am new to glow and new to TTC.

My SO and I have been trying to conceive since January. I have had three 28-29 day cycles since going off the pill. Af is now 3 days late.

I have been experiencing mild cramps beginning a few days before af was expected which is pretty normal for me, but they have stayed mild which is not normal. My breasts have felt Itchy and tender.

Today I felt nauseous in the shower. A couple hours ago I started to feel a pulling sensation.

I haven't tested as I was trying to wait until I was a week late, but now I am not sure if I could have a uti?

Thanks in advance for your time and support.
