Problem In Conceiving

I had first baby 3 years ago by c section. I took gap of 2 years and never used any pills or injection for this purpose. After 2 years I tried for next baby but didnt conceived. Its been about one year I started trying, i n this regard I consulted one gynecologist who after ultrasound told that there is nothing wrong with me. Every month I feel chest and back ache which persists the whole month and relieves with the onset if periods. I want u to suggest me something for easy conceiving. Moreover my husband lives in another city and he's back on weekends. I want ur suggestions regarding the whole matter in details.
