Hello,
Thanks for writing to Health Care magic, I am Dr , Muhammad Ahmad , I have read your question closely, I understand your concern and will be helping you with your health related problem.
Delay in Periods don't necessarily mean
pregnancy but there is a way to know best which i am going to suggest you here.
According to the circumstances you told in your question here is the best way to deal with this thing.
Repeat UPT test at home in next week and then in the week next to it.
Till then if you don't get any period and you are still negative on the poregnancy test then it is more appropriate to get a blood pregnancy test, if that too is negative then you can discuss this with your doctor and you can get other investigations done like
hormonal levels and
ultrasound, this can help in the diagnosis and proper treatment will definitely imporve things further.
I hope this answered your question, If you have more queries I am happy to answer you.
Regards.
Dr.Muhammad Ahmad
