So I had a chemical pregnancy in August. In September I had pink spotting two days before my period was due then my period came two days late, bright red from on onset. I don't normally bleed irregularly and it usually starts brownish and very light. Do you think the pale pink spotting was my period arriving but didn't start full flow for a few more days? I ask because I want to work out my next period date. At the time I wondered if the pink spotting was implantation bleeding but then assumed possibly beginning of period. Thank you.
