Hi, thanks for using healthcare magic
Symptoms of early pregnancy
are breast tenderness like you are describing , as well as, nausea
, mild abdominal discomfort.
Home pregnancy tests detect the level of HCG in the urine, some tests detect lower levels of hormone , these are the early detection kits. You can try to use these kits.
Another option would be to have a blood level for the hormone.
Hope this helps
