What does it mean when have lower abdominal pain and feels like bubbles in my pelvic area but its anit gas?

Constipation?: Sometimes, constipation may present with a feeling of bloating or"bubbles" in the pelvic area. I see you are taking iron supplements which commonly cause constipation. Consider seeing your doctor for a proper evaluation.

Many things...: Possibilities include constipation, tubal problems, endometriosis, ovarian cysts, infections, colon issues, diverticulitis, tumors, etc, muscle strains, herniae... even pregnancy!! You should see your doctor who will do a thorough exam, take a good history and maybe order some studies.
