Pregnancy symptoms?

Malorie • Trying for baby # 1 on month 11 now.
I am not pregnant .... Yet and was wondering what some of your symptoms were I have had a bubbly sensation on my lower left side for about a week now. My breasts are really tender and lower back started to hurt today.  Don't want to think to much into this. Been getting positive opks all week long. Thoughts!?!
