Ovulation & Period after a miscarriage???

Shana
I had a miscarriage on 4/23. I got a positive CBAD opk flashy smiley face (high) on 5/5 for 7 days & got a low and the 12 & 13th then high again on the 14th - 17th & stopped testing because I was getting frustrated. I started cramping on the 4/22 took another opk & got a solid smiley face so I finally peaked on 4/22. Still no sign of AF. I've been very emotional these past few days, crying & cramping back pain, fatigue & lots of acid reflux and lots on CM. I feel wet sometimes & i think its AF but its not its just discharge. Took several hpt & all BFN. According to the apps in 12days late if I count from the last day of bleeding from back in April I'm just frustrated in this waiting game.
