DirectX 11 Not Drawing Small Vertex Buffer - c++

Question

I have a problem with my DirectX app. It can't draw primitives like D3D11_PRIMITIVE_TOPOLOGY_POINTLIST or D3D11_PRIMITIVE_TOPOLOGY_TRIANGLELIST when vertices count relatively small value(3 Points to 100 points). Over thousand vertices, it suddenly draws lots of primitives. But not sure it draws them all.
My code looks likes this.
Main Code:
Fill Vertex Array
OurVertices = (VERTEX*)malloc(PointCount * sizeof(VERTEX));
for (int i = 0; i < PointCount; i++)
{
OurVertices[i] = { RandOm() * i,RandOm() * i ,1.0f ,{abs(RandOm()),abs(RandOm()),abs(RandOm()),1.0f} };
}
RandOm():Random value from 0.0f to 1.0f. Multiplied by i to get some realistic world coordinates.
Vertex Buffer
D3D11_BUFFER_DESC bd;
ZeroMemory(&bd, sizeof(bd));
bd.Usage = D3D11_USAGE_DYNAMIC;
bd.ByteWidth = sizeof(VERTEX)*PointCount;
bd.BindFlags = D3D11_BIND_VERTEX_BUFFER;
bd.CPUAccessFlags = D3D11_CPU_ACCESS_WRITE;
dev->CreateBuffer(&bd, NULL, &pVBuffer);
VERTEX: struct VERTEX { FLOAT X, Y, Z; FLOAT Color[4]; };
Mapping
devcon->Map(pVBuffer, NULL, D3D11_MAP_WRITE_DISCARD, NULL, &ms);
memcpy(ms.pData, OurVertices, PointCount* sizeof(VERTEX));
devcon->Unmap(pVBuffer, NULL);
devcon: ID3D11DeviceContext
Render
float color[4] = { 0.0f, 0.0f, 0.0f, 1.0f };
devcon->ClearRenderTargetView(backbuffer,color);
UINT stride = sizeof(VERTEX);
UINT offset = 0;
devcon->IASetVertexBuffers(0, 1, &pVBuffer, &stride, &offset);
devcon->IASetPrimitiveTopology(D3D11_PRIMITIVE_TOPOLOGY_TRIANGLELIST);
devcon->Draw(PointCount, 0);
swapchain->Present(0, 0);
Shader
VOut VShader(float4 position : POSITION, float4 color : COLOR) {
VOut output;
output.position = mul(world, position);
output.color = color;
return output; }
float4 PShader(float4 position : SV_POSITION, float4 color : COLOR) : SV_TARGET {
return color; }
XMMatrixOrthographicOffCenterLH calculated applied using CBuffer as can be seen on shader world variable. I think Orthographic projection works fine from my visual observations. There are neither CPU or GPU exceptions. And no warnings.
Rasterizer
D3D11_RASTERIZER_DESC RasterDesc = {};
RasterDesc.FillMode = D3D11_FILL_SOLID;
RasterDesc.CullMode = D3D11_CULL_NONE;
RasterDesc.DepthClipEnable = TRUE;
ID3D11RasterizerState* WireFrame=NULL;
dev->CreateRasterizerState(&RasterDesc, &WireFrame);
devcon->RSSetState(WireFrame);
Orthographic Projection
ID3D11Buffer* g_pConstantBuffer11 = NULL;
cbuff.world = XMMatrixOrthographicOffCenterLH(SceneY - (ViewPortWidth / 2)
* SceneZoom, SceneY + (ViewPortWidth / 2) * SceneZoom,
SceneX - (ViewPortHeight / 2) * SceneZoom, SceneX + (ViewPortHeight /
2) * SceneZoom,-10000.0f, 10000.0f);
D3D11_BUFFER_DESC cbDesc;
cbDesc.ByteWidth = sizeof(CBUFFER);
cbDesc.Usage = D3D11_USAGE_DYNAMIC;
cbDesc.BindFlags = D3D11_BIND_CONSTANT_BUFFER;
cbDesc.CPUAccessFlags = D3D11_CPU_ACCESS_WRITE;
cbDesc.MiscFlags = 0;
cbDesc.StructureByteStride = 0;
D3D11_SUBRESOURCE_DATA InitData;
InitData.pSysMem = &cbuff;
InitData.SysMemPitch = 0;
InitData.SysMemSlicePitch = 0;
dev->CreateBuffer(&cbDesc, &InitData,&g_pConstantBuffer11);
devcon->VSSetConstantBuffers(0, 1, &g_pConstantBuffer11);
