Awaiting AF after MC

GF
I don't think time could pass more slowly. I miscarried on May 12 and bled for 9 days. Based on CM I think I did ovulate again around the 29th or 30th of May. If that's the case AF should have started around the 10th of June. I've had three days of lower back pain, lessening each day. If I (tmi) wipe inside a bit when I pee there is the slightest hint of pink as when pregnant and the cervix has more blood, not so much like when AF is coming. Thought I had a faint metallic taste in my mouth today which I had with 3 out of 4 prior pregnancies. Going a bit crazy waiting, just want it to start so I can feel normal again and silence the questions in my head. 😣
