I can't say I've ever heard of that particular brand of Calcium. If you have a local health food store anywhere in
your area, they may be able to help you with that, or direct you to a nutritionist if you're interested.
As Ego suggested it would be helpful to see your doctor for a checkup & to have some bloodwork run, as it will give you the concrete information needed for you to decide your next step.
Please look up further phosphorus info online, as the following site provides material you might want to check:

Phosphorus
Phosphorus is an essential mineral that is required by every cell in the body for normal function (1). The majority of the phosphorus in the body is found as phosphate (PO4). Approximately 85% of the body's phosphorus is found in bone.
Function
Phosphorus is a major structural component of bone in the form of a calcium phosphate salt called hydroxyapatite. Phospholipids (e.g., phosphatidylcholine) are major structural components of cell membranes. All energy production and storage are dependent on phosphorylated compounds, such as adenosine triphosphate (ATP) and creatine phosphate. Nucleic acids (DNA and RNA), which are responsible for the storage and transmission of genetic information, are long chains of phosphate-containing molecules.
A number of enzymes, hormones, and cell-signaling molecules depend on phosphorylation for their activation. Phosphorus also helps to maintain normal acid-base balance (pH) by acting as one of the body's most important buffers. Additionally, the phosphorus-containing molecule 2,3-diphosphoglycerate (2,3-DPG) binds to hemoglobin in red blood cells and affects oxygen delivery to the tissues of the body.
Fructose -
A diet high in fructose (20% of total calories) resulted in increased urinary loss of phosphorus and a negative phosphorus balance (i.e., daily loss of phosphorus was higher than daily intake). This effect was more pronounced when the diet was also low in magnesium. (High fructose corn syrup is often found in many products {this includes soda, Miracle Whip, etc.} & may well be a contributor in obesity & possibly diabetes). This study's finding is relevant because fructose consumption in the U.S. has been increasing rapidly since the introduction of high fructose corn syrup in 1970, while magnesium intake has decreased over the past century.
Recently, a controlled trial in young women found no adverse effects of a phosphorus-rich diet (3,000 mg/day) on bone-related hormones and biochemical markers of bone resorption when dietary calcium intakes were maintained at almost 2,000 mg/day.
At present, there is no convincing evidence that the dietary phosphorus levels experienced in the U.S. adversely affect bone mineral density. However, the substitution of phosphate-containing soft drinks and snack foods for milk and other calcium rich foods does represent a serious risk to bone health.
Deficiency
Inadequate phosphorus intake results in abnormally low serum phosphate levels (hypophosphatemia). The effects of hypophosphatemia may include loss of appetite, anemia, muscle weakness, bone pain, rickets (in children), osteomalacia (in adults), increased susceptibility to infection, numbness and tingling of the extremities, and difficulty walking.
Food sources
Phosphorus is found in most foods because it is a critical component of all living organisms. Dairy products, meat, and fish are particularly rich sources of phosphorus. Phosphorus is also a component of many polyphosphate food additives and is present in most soft drinks as phosphoric acid.

Tolerable upper intake level for phosphorus:
Adults 19-70 years 4,000 (4.0 g)
As to the loss of periods that is yet another subject altogether. I don't know how often an IUD would affect whether you get your period, as your doctor stated. But there are many other reasons for it to stop early, though at your age, it seems surprising that it's been 5 years. It may not be a bad idea for you to consider having a hormone test done for yourself as well as having other blood work done to see if other things are going on too.
Lack of estrogen can be the reason why you are not getting your period. This can create a health concern that requires medical attention. This is because estrogen is necessary to build strong bones. (Female athletes who don't get their periods, for example, suffer more stress fractures than those who menstruate.) Women who are to thin, & or are to low in body fat levels sometimes do not get their periods.
During the reproductive years if you are not having periods there is something out of balance in your body. This needs to be investigated and treated. For one thing, if you are not having periods, your risk of osteoporosis is greatly increased.
As you can see, it is very important to go further than your doctor has done thus far. If he or she is unwilling to do more investigation, then by all means find another practitioner to do so.
Good Luck to you & I hope you start feeling better soon.
