i suffered from severe lower abdominal cramps jut after having intercourse. i went to the Dr a pelvic scan was done which showed fluid in the Pouch of Douglas and was given Ciprofloxacin and some painkiller for a week. i went back again after about 3 months and the fluid was still there. this happened every now and again not everyday. now that my husband is away i dont feel the pain at all its only felt soon after intercourse.
