I am a married lady and trying to conceive, my periods were due on 21 June 2013, but get delayed, I usually have 28-30 days cycle, but over the last few months of 2012 I had long periods of almost 10-12 days, so my gyn has prescribed oral contraceptive (21 day course) and for last three months(March/April/May) they are on time and lasts for 5 days.Then I had clomid tab and a hcg shot in April 2013, I had regular period in May 2013 but in June they are now delayed by 14 days, my HPT (urine test: 2 times) is negative so I went today to my gyn but he told me that there is no point in waiting, you are not pregnant and given me tab Primolut. I still want to wait as I have heard that sometimes HPT are false. Please advice how can I be sure whether I am pregnant or not.
