Lower left pelvic pain

Last night I started to have a kind of dull pain in the lower left side of my abdomen. The pain is worse when I lie on my side. I don't have pain when I urinate, so I don't think it's a UTI. I am about 7dpo and not ttc. My breasts have also been sore, my abdomen feels taut, and my sex drive has disappeared for the last few days, but not sure if those are related. Anyone had a similar experience?
