Good morning to Health Care Magic.
You are 22 yrs married women and missed period by 1wk.
So better to do a home pregnancy
test with urine and check the result whether you pregnant or not.
If test result becomes negative,you may wait for few days to get your period and do a blood test
to exclude pregnancy.
There are several reason of missed period with exclusion of pregnancy.So don't be upset. Follow the above advice.
If need any suggestion,mail me...my id email@example.com
All the best.
