My daughter was on the omni diet. she took 4 pregnancy tests and they have all came back positive. she was told there is not enough hcg in the drops.

Maybe pregnant: If she was taking unregulated nonFDA approved BHCG drops then it is hard to know. If the home tests are positive then one has to assume it is a real pregnancy before assuming it is a side effect of a diet supplement. She should see an Obgyn for confirmation.

Pregnant?: Your daughter is probably pregnant. The amount of Hcg in the drops is not supposed to be enough to turn a pregnancy test positive. If these drops are still for sale, there is probably no HcG in the drops because selling over-the-counter HcG drops is actually illegal. There is a lot of misleading labeling. But if you look closely, there may be NO hcg. A blood pregnancy test may help.
