Venting late period 18dpo

Well my period is 5 days late at 18dpo for the first time ever. I went to see my doctor only to find out I'm not pregnant. Cd31 and endometrium is only 5 mm. I'm waiting for blood results to see what is wrong. We are scheduled for the ivf 11/2020 after ttc for 2 years and for split second I thought that maybe just maybe God answered my prayers but NO! No no no and its always a no for me. I'm just sick from all of this. Angry,disappointed,sad..sitting here and crying like a baby (haha) cuz my life feels miserable right now.
