Thanks for asking. The symptoms you describe corroborate with dysmenorrhea. Many young or middle age women might experience it. Many of the cases are managed easily with birth controlled pills. If it is not improved with this strategy more investigation is needed. If you have pain at the time of defecation or intercourse it might be endometriosis
although the chance is pretty low.
When a lady is pregnant and experiences spotting, its frequency is not regular. In those cases a severe pain
experienced which is not related specifically to the time of bleeding. I hope that this information helps. I am eager to hear from you back.
