Pain in lower Left abdomen.. Help

Jackie
Hi there ladues, this is my first time posting, but I am extremly clueless. Two days ago I had somewhat severe pain in my left lower abdominal area, So severe I had to lay in the fetal position. Glow says Im ovulating, So I thought nothing of it, thinking Ovulation Pain. But the next day I woke up the pain was still there ( Not so severe). This morning I woke up with very tender breast and Nausea. I have not taken a HPT yet, not sure if I should. My period is about 16 days away. Me and my husband have been TTC for 4 years.. Has anyone felt this pain or no what the cause could be.
