there are many possible reasons for the symptoms that you describe. since you had your period, pregnancy
is unlikely, but sometimes temporary fluctuations in hormone levels can cause these types if symptoms. usually, these issues will resolve on their own in a few days, and I usually advise patients to wait a little to see if things just resolve on their own, if this persists though, you should get it checked. then your doctor can check levels of hormones such as prolactin
hormone and others. changes in these hormones can cause these symptoms and sometimes require treatment.
I hope this is helpful, please let me know if you have any more questions.
