I have had a rollercoaster of a week- found out I was pregnant on the Saturday, started bleeding on Sunday, had a stay in hospital because they thought it was ectopic, turned out to be MC which was confirmed yesterday. My CBFM arrived the day I had my BFP so I thought HA! I don't need it! But now I do 
Does anyone know how long you should wait to start using it? Docs say you should wait for a period before TTC to make dates easier- would this work for CBFM? Any thoughts/advice/experience gratefully received!
