can anyone help figure out where I am in my cycle?

I had a miscarriage that started on 10th September... long story short I had a scan on 29th September and I had a scan that showed I had some placenta that still had a blood supply so had to get that treated and my ovaries looked good on the scan. I then went back for another scan on 7th October which showed everything was gone as it should have and I had cysts forming on my ovaries which was a good sign that I was going to ovulate soon. I stopped bleeding from the miscarriage on 19th October and we were able to start ttc again. I'm keen to know where in my cycle I am so I can figure out if I stand a chance of being pregnant or not or if I was still bleeding when I ovulated. Also it's nice to have half a clue when AF is due. Thanks in advance and sorry for such a long post!!
