Yesterday afternoon I felt this horrendous sharp pain in the lower left side of my abdomen as if I'd been stabbed with a knife. I rang my OB & raced in to see him & he thinks I've ruptured my corpus luteum cyst on my left ovary. The pain has been so horrible. Good news is, baby is OK with a strong heart beat.despite this I can't help but feel nervous about miscarriage now. Has anyone else experienced this?
