Hello ma'am and welcome.
You have failed to mention your maritsl or sexual status, but assuming that you are considering pregnancy
to be a possible cause, this must be positive.
Ofcourse, I would first recommend a home pregnancy test to be conducted using an early morning urine sample. You could repeat this test 2-3 times every alternate day to yield a confirmed result.
If at all pregnancy is ruled out, then we will have to find the cause for your symptoms as you are clearly experiencing a hormonal
imbalance. Please report to your doctor st your earliest convenience as you are in pain.
Hope this helps.
