I had pcos nd did three month course with krimson 35 and medical prescribed for 2 months and added cor 3 in 3rd month. Now this month I am trying for conception nd letoval was prescribed along with medical, ecosprin, duphaston nd cor 3.letoval to consume from 3rd day and duphaston from 17th day. I had completed 5 day letoval consumption but on 5th day I am feeling fatigued, while body aching esp back pain nd leg pain and some strange stomach cramps like period cramps in between with a nauseous feeling nd mild diarrhea nd headache. On 6th day I am better but my back ache is lesser nd stomach cramp intensity in lesser but still persists. Is it normal or related to this course or letoval or there might be other reasons for these stomach period like cramps nd pains occurring in between?
