Hello, this would be my 3rd. I took a test last Fri (day before AF due) and got a faint +ve. Was due to see GP this morning and had a wobble and took another test (actually two), the First Response was still +ve but very faint (possibly fainter than original test 6 days ago) and the CB Digi said 1-2 weeks when it should have said 2-3 weeks. I'm at 19dpo today and surely should be seeing big fat positives by now? Certain of dates because I temped and use CBFM. Obviously my worry is that HCG levels are not rising and this pregnancy isn't viable. I've cancelled GP appointment because I'm fearing the worst. Feel in awful limbo now. What shall I do? I guess I've no choice but to sit at out and test again in a few days.
