My husband and I have been trying to conceive within the last 3 years or so. I have an irregular period and my doctor first put me on birth control pills or regulate my period. So far in the last year or so, my period has become normal, coming in at least once every two months, before it was 3 or 4 times a year. I am currently on my period, so I know that I am okay, but my worry is my husband. He has been taking heavy medication for his back pain, medication that contains codeine and all. We have great sex and he does ejaculate inside of me, but with his heavy medication intake and plus smoking, is this one of the causes of his low sperm counts? It breaks my heart when I see everyone around me getting pregnant except me. We are also a young couple, I am 24 and he is 28.
