Hello and welcome to HCM.
Thank you for your query.
I have gone through your query and would like to speak about the two most likely causes.
First, we will have to rule out
pregnancy, as this has to be done in all such cases. I would request you to repeat a urine pregnancy test again, and this time with an early morning urine sample, which would yield the most accurate result. If this was not already done.
The next fact is your age. At 46, you are approaching
menopause, and around menopause all such symptoms are experienced by many women. But, we will have to confirm this.
I would thus request you to visit your doctor and get examined, just to be on the safer side. Wishing you lots of luck and a beautiful life thereafter.
I hope I have succeeded in providing the information you were looking for. Please feel free to write back to me for any further clarifications. I would gladly help you.
Best wishes.
