 [ Symptoms ] what might cause excessive bloating and pelvic pain other than constipation  last week i woke up one morning with my belly protruding so much that i look suddenly in a 2nd trimester of pregnancy thinking it might be constipation i started taking fiber drinking lots of water and eating more yogurt i am not having any issues with hard or infrequent movements however now the problem has progressed to include pelvic pain like bladder and hurts with sudden movements as well as moderate burning on one side like around ovary area i am confused and concerned [ Disease ] hi first of all get confirmation done that whether she has deep vein thrombosis or dvt or not then you can worry about the anti coagulants so first get tests done like d dimers test ultrasound venography etc if it is confirmed then you can discuss about new generation of anti coagulants and appropriate dose titration can be done so that she does not suffer complications like excessive bleeding hope this helps
