When is the right time to use hpt?

Question

My period cycle ranges from cd28-cd34 so when do I begin hpt? cd29 or cd35? or should I juz until cd40 and see if AF comes?

Answer 1

the rule of the thumb is to test teh day after your next expected period is due, and so i would wait until day 35 at least and use first morning urine also--contains the highest level of the pregnancy hormone--hcg.
