Hello dear
Understand your concern
Do not worry.
Your period will be delayed due to Unwanted 72 as it cause hormonal imbalance. Unwanted 72 contain high progesterone that lead to prolong the second phase of cycle and lead to delayed period by 7-10 days.
Bleeding on the 26th august is a breakthrough bleeding and it is progesterone withdrawal bleeding.

If period will be delyed by 12-14 days then again go for HPT in early morning with fresh urine and or by blood HCG to exclude the pregnancy as unwanted 72 has 5 % failure rate.
In absence of pregnancy, period can be induced by prinolut N under the guidance of gynaecologist.
Hope this may help you
Best regards
