Thanks for the query.
I understand your concern. Irregularities in menstrual cycles can occur due to many causes like lifestyle modifications, polycystic ovary disease, gonadal or thyroid hormonal imbalance, prolactin level changes etc.
Pain during intercourse can occur due to causes like pelvic inflammatory disease, retroverted uterus, prolapse of ovaries into pouch of Douglas etc.
Sometimes pelvic inflammatory disease can also present with irregular menstrual periods by affecting the internal reproductive organs.
As all your urine pregnancy tests gave negative results the possibility of pregnancy is less.
So, please do consult your doctor, get examined and go for investigations like ultrasound, gonadal hormonal profile, thyroid hormonal profile, prolactin levels, hemoglobin and blood sugar levels estimation etc.
With this workup, the possible cause of your problem can be identified and treated.
Hope this helps.
