I wouldn't worry too much about that. I drank plenty of diet cokes with artifical sweeteners and my kids were fine. 

I drank diet drinks as well, but that is aspartame, not cyclamate.

We lost our little one (my third loss now) but that will not stop us from trying again.

I'm sorry to hear that!  Definitely keep trying.  It definitely is possible to have a healthy child and a healthy pregnancy. Just be sure to have your sugars in check prior to getting pregnant and during.

In 1966, a study reported that some intestinal bacteria could desulfonate cyclamate to produce cyclohexylamine, a compound suspected to have some chronic toxicity in animals. Further research resulted in a 1969 study which found the common 10:1 cyclamate:saccharin mixture to increase the incidence of bladder cancer in rats. The released study was showing that eight out of 240 rats fed a mixture of saccharin and cyclamates, at levels of humans ingesting 350 cans of diet soda per day, developed bladder tumors. Other studies implicated cyclohexylamine in testicular atrophy in mice. On October 18, 1969, the Food and Drug Administration citing the Delaney Amendment banned its sale in the United States and the United Kingdom followed suit the next year. Abbott Laboratories claimed that its own studies were unable to reproduce the 1969 study's results, and in 1973, Abbott petitioned the FDA to lift the ban on cyclamate. This petition was eventually denied in 1980 by FDA Commissioner Jere Goyan. Abbott Labs, together with the Calorie Control Council (a political lobby representing the diet foods industry), filed a second petition in 1982. Although the FDA has stated that a review of all available evidence does not implicate cyclamate as a carcinogen in mice or rats, cyclamate remains banned from food products in the United States. The petition is now held in abeyance (it is not actively being considered) though whether this is at the request of Abbott Labs themselves or because the petition is considered to be insufficient by the FDA is unclear. Cyclamate is approved as a sweetener in more than 55 countries: for example, the brand-name beverage sweetener Sweet'N Low, which contains only dextrose, saccharin, cream of tartar, and calcium silicate in the United States, contains cyclamate in Canada (where saccharin is banned except for diabetic usage). Similarly, Sugar Twin, the brand-name cyclamate sweetener in Canada, contains saccharin in the United States^[1]. (October 1969)
