Please comment- ovary pain

Pip • Pregnant with a little boy • c-section is booked for 4th July 2016 at 8am ✨
I'm just wondering has anyone felt this way with very early stage pregnancy. I haven't had a positive pregnant test yet. But I have very sore boobs especially nipples and I have this pain in my left ovary. I've never experienced this before, it's also painful during sex. Has anyone experienced this? Comments would be appreciated.
