Hello I’ve already seen a gynaecologist who has suggested birth control pills but look to see if I can get any more advice. periods are going on for 12 days and then now by 17th day I’m having cramping stomach ache and nausea probably preparation for next period which is coming by 24th day. Anyone had similar experiences?? like I said I have gone to gynaecologist who has given birth control pills but still this is too much to even tolerate combined with the heaviness. Someone must have gone through this. I have not started the birth control pills yet as I was afraid.
