Not sure what this means...

I had an early MC 11/4... I was entering my 7th week, my baby failed to develop but my egg was fertilized. This is my first time experiencing a miscarriage. We have been trying for a year, for baby 2 ... our DD took 5 months. I started getting impatient since it's been a year, so I started to use this app (I really like the forum support) and track better... we got pregnant not even a month of using this and the book 'sperm meets egg plan' it's free on kindle.. and it sadly ended in MC. My hcg levels dropped from 205 Tuesday (11/4) to 45.65 following Friday the same week 11/7 (bleeding seceded); I took a htp test that detects 25ml hcg it was negative 11/10. My actual period date if I wasn't pregnant would of started 11/11. I don't get it and I know my 'whys' will never be answered, only the Lord knows. I know I tried to control this situation, but I also knows everything happens in His timing, not my own... Bc I tried to track and control ... guess I just have to give it to God, put it all in His hands this time. And trust He knows what's best.

So now I can really track accurately bc of my MC. I entered it as a period it was the same days and same flow like my normal period only came exactly we week early this month of November 11/4 instead of 11/11. I haven't bought ovulation strips but from some other calculations if 11/4 was recognized by my body as a "period" my fertile week would of been the 13-18th or so. We BD every other day from the 11/11. My BBs are sore feeling today and won't stay in my bra...this is what happened last month few weeks before I found out I was pregnant.

Are sore BB an indication of ovulation has happened, fertilization of the egg, or what? ...What would that possibly mean. I'm not crampy like a period is gonna happen, my Boobs don't get sore before a period either. ???? HELP ... anyone have this happen?
