Hello mam, thanks for trusting health care magic.
in my opinion do a urine pregnancy
test and see for result it can be early pregnancy.
in case test is negative wait for a week for periods and in case you still dont get them, visit a gynecologist
In case you have further questions you can consult me on health care magic forum and i will be happy to help
Take care and wish you all the best.
Dr Manisha Jain.
