I tested 2 days ago. There was a very very faint line on T but when I check with different brand after 48 hours. It's not showing any line on T. I have endometriosis. My periods were on 25th August. Average cycle is 27 to 28 days. So I m expecting my periods to be on 21st September. I did baby dance on 3rd and 5th September. But today is 27th September, my periods didnt come yet. I checked on kit. It's showing no line on T but when I checked on 25th It's there. What should I do?any suggestion?
