Your symptoms suggest some infection in the pelvis. If you have had a normal period and have not been sexually active recently, please exclude infection through blood counts, urinalysis
and pelvic/trans-vaginal sonogram. If you have been sexually active, please exclude pregnancy
and a possible inevitable abortion. Constipation
can be seen as a symptom of progesterone
effect along with bloating, but not always. It may also be due to some gastro-enteric cause. Hope this helps.
