Chart after miscarriage

I usually ovulate on CD 13-15. I had all the symptoms last weekend (feb. 23-24) and assume I O’d on Feb. 24. Normally my temps are higher, but wondering if it changed b/c of miscarriage. I assume I am about 10 dpo, but started cramping and spotting last evening. I have no idea what’s going on and AF is not due yet.

Please help me. I’m still new at this. Thanks!

Updated the chart as I just had a huge shift this morning at 12 dpo? I am still spotting, but still no AF and no BFP. So confused!!
