I have been having irregular periods,then I did some tests like hsg,homonal profiling, tvs, then I was given metformin, clomid,and hcg shot to trigger ovulation, then 3 days to my period that s 12 days after ovulation I spotted brownish discharge, and I have been feeling feverish too, now am 2 days late and no tender breast, or other signs. Could I be pregnant?
