I had taken my HCG injection on 18th Oct 16, My last menstruation date was 2nd Oct 16. I usually have a cycle of 29-30 days. I am also having progesterone supplement. When should I be expecting my period. I am trying to conceive. 2 days back I had bad backache and abdominal pain but no sign of periods and the HPT is negative. Please suggest.
