If you are pregnant this could account for your symptoms.
If your period has started again and you are not pregnant, such symptoms can be related to
excessive weight loss or gain
thyroid problems [and these are not typically tested for on routine blood work]
Liver or kidney disease.
Other hormonal problems [an adrenal panel and sex hormone panel are needed].
Regular blood tests cover liver and kidney disease, if a urinalysis was also done.
They don't cover the rest.
I would talk to your doctor again.
