Hi ladies
​I just want to get your opinion on this...
​I'm 12 DPO today -AF due today but no sign.
​I know this isn't positive as the line isn't as strong as the control so can't get excited but just wondering what ladies who have been through this and then had strong BFP think..
​Let me know please. Thank you ?
