Delayed period post-miscarriage

Natalie • TTC after 4th loss | March ‘18 💙 Dec ‘15 💙🧩
After my first early pregnancy loss, I had a seemingly normal period.  I figured things would be the same after my second loss, but instead I'm anxiously waiting for AF like a late blooming tweener.  Where is my period?  I'm ready to get back to TTC.
​My cycles have always been very normal, easy, and on time.  Anyone else have a delayed period post miscarriage?  What was your experience like?  My OB told
​me to expect mid-cycle bleeding and a heavier period to come, but he didn't mention a delay.  I'm over a week late and feeling so frustrated and disheartened.
