Lower abdominal pain

Natalie • 22, Married & mother to my beautiful Ayva Raylynn.. Pregnant with baby #2 :) baby dust to all of you beautiful ladies!
I'm 5-6dpo not exactly sure, but I'm having lower abdominal pain almost like if I've been holding my pee for a long time? It only hurts on my right side and it's right below my stomach and next to my hip done. When I have the urge to go pee it hurts a little stronger then goes away after I pee but still lingers. Doesn't burn or itch when I pee..
I'm just a little confused as to what it could be feels "full" and achy
It doesn't feel like a UTI at all
The only other symptoms I've had is a tad bit of breast tenderness, and achy lower back
And help ladies?
