I have a question re spotting before period. It occurs approx 4 days prior to period every cycle. I am wondering if this would be due to low progesterone or possibly a lutal phase defect? I have done 1 icsi round - negative (spotting started 11 days past transfer - using progesterone pesseries ) and 1 natural fet - negative (spotting occured 5 days past transfer). Any info would be appreciated.
