Hi welcome to Health care magic forum.
Thanks for choosing H.C.M.F.
According to your description the pain is there only during the ovulation period and it is going to be worse upto the period (i have assumed) As you said there is no appendicitis
or kidney infection
, or gastro intestinal problems.
So it appears that you are missing gynacologist , The pain appears to be dysmenorrhoea due to pelvic inflamatory disease, or p.c.o.d.etc. So i advise you to consult a gynacologist for diagnosis and treatment.
You may need to have trans veginal ultrasound
scanning, besides other routine tests for confermation.
Wishing for a quick and complete remission form the disease. I welcome to call me for any doubts in this matter.
