Low pelvic pain

So I have this awful sharp stabbing pain where the red circle is. It’s been going on for about 10 minutes, I’ve tried drinking water, reclining on my couch, laying on my left side. Nothing is making it go away and it hurts very badly. The black circle is where I felt pain last night, sort of similar, but it passed very quickly. What the heck is going on with the right side of my body? 28 weeks.
