Dear J. S.,
I was married for almost 12 years before my active duty husband and I had children. We now have 2 wonderful girls, 8 & 4. We used the Norplant and I had a great experience with it. My cycles were longer, which was fine with me. Only draw back was my period would last longer than normal, sometimes 10 days to 2 weeks. It was never heavy but enough that I would need a pad. It was a great birth control mode for 5 years (or 50,000 miles we would jokingly say) Insertion and removal were relatively easy-local anesthesia was required. Think long and hard if you want the 5 year limits though. You sound as though you wouldn't mind another child, wouldn't we all. Due to our age we decided 2 were enough for us. We are 47 & 49 now.
Best of luck with your decision.
S. C.
