Hi,
If you have been sexually active without protection all through, you should definitely exclude
pregnancy. You may take a HPT with a fresh early morning sample, or go for a
blood test and a sonogram.Other reasons for the delay in the period could be the
hormonal imbalances you had in the last month. Your symptoms can relate either to early pregnancy or be pre-menstrual. Please contact your health care provider for further support. Take care.
