We are ttc on our second child, recently had Mirena Coil removed, (March 2019) no sign of AF due yesterday, 28 day cycle and so regular to the hour, took a test yday afternoon and line was so faint barely visible, took one this am and a little darker but again barely visible :/ is all ok? I would have thought at this stage 15dpo the line would be darker, I have had 2 previous mc so maybe this is my reason for concern? any help or advice appreciated? ps. cheapie poundshop test used.
