Prayers needed

Went in for a vaginal ultra sound yesterday 6weeks. They saw nothing. Absolutely nothing. Pregnancy tests still coming out bfp. Last night I had the worst pain ever on my right side. And started to bleed. This would be my 3rd m/c. Doc said everything looked fine with my ovaries, cervix, and uterus. She said its probably just to early to see anything. Have to go again on Monday for blood work.
So I'm incredibly confused and emotionally tired. Advice and prayers needed please. I feel hopeless.
