I am 28 and my husband is 36 .. all reports are normal and Due to unexplained infertility, we had to go for iui Doctor gave medicine and injections for ovulation induction and i had double iui on 12th and 13th day of my cycle and had been using progesterone suppository and estradiol for 14 days I tested with prega news on 14th and 15th day it is  very faint positive and negative on 16th. My due date is on 10th july i didn't get my periods ? Should I repeat pregnancy test or periods are delayed due to progesterone. I m confused.
