period due 2/24

Hope
I'm 7dpo, due for period 2/24 but my OB said to wait until 2/27 to test if no AF
I had an MC 8/2016 and this has been my first "normal" cycle since and I have 0 symptoms of being pregnant where as last July I had symptoms starting as early as 4dpo. Why does ttc have to be so frustrating?! Anyone else due for their period on 2/24 and on the frustrated train with me?
