At age 22, you almost certainly still have hundreds of thousands of eggs in your ovaries - they just are not being released. In general, regular monthly ovulation requires that a critical % of a woman's body weight be fat - approx 20%. Thus, once you reach full recovery, you will hopefully start having regular periods again when not on the pill. However, if this does not occur, then you would need injections of fertility drugs to achieve ovulation, which should be accomplishable pretty easily if required. As for the need for a gestational surrogate, you probably could carry on your own; the high estrogen levels of pregnancy if anything would do good things for osteoporosis. The answer to your question about a surrogate, with your husband's sperm and your eggs being possible, is 'yes' and in fact this is a very frequent arrangement. I am just not sure you will need a surrogate.
