welcome to health care magic
do not worry. if her period is delayed by so many days then i suggest that you should get a blod test,serum beta hcg
titre done.this test will tell you about the pregnancy
status. even if she is pregnant and you do not want the baby now, there is a way. some tablets can be taken. however these should be taken under the supervision of a certified gynaecologist and not on your own from a chemist.get the serum beta hcg titre done and then we'll take it from there. please mail me if you need further advise.
