Help I need advice asap PLSSS!!!


So I had a normal period last month from the 24 to the 28 and a couple days ago I had some pain on my left side abdominal area and I spotted when I went to the bathroom. It stopped that same day but I still had pain. Now it started again and I still have pain. It's like a sting burning almost stabbing sensation. It's starts small then goes up and goes back down. What can it be????

I also NOT on birth control. Never been

Ladies help me.
