Pls help! Could this be pregnancy?

On CD 14 i had pain on one side of my lower abdomen, it wasnt severe but i wasnt comfortable and I had to take a pain killer to sleep. I also couldnt sleep on my tummy. 
If this is ovulation pain, it is soooo not common for me! I only felt like this on my firsr and only pregnancy (ended with a mc).
I am CD20 now and have swollen breasts, lights cramps and backache, pain in legs when i stand up for a while. 
Could this be it? Could I be finally pregnant?
