Hi everyone, I'm new to mumsnet but I'm wondering if someone can help me... I've been driving myself crazy for the past week or so! I had a miscarriage in February (TTC number 2 - my oldest is 18 months) and felt utterly crushed then hugely impatient to get pregnant again. I used OPK and had flashing smiley face for nearly 2 weeks (I know advice is not to use them immediately after a MC but I really didn't want to miss ovulation!) I got a positive static smiley opk on 5th March. TWW was agony, and now I've been testing negative since about 10 dpo. (I've gone a bit overboard really... I'd be embarrassed to calculate how much I've spent on tests! I might have a POAS addiction.) I'm now between 16 - 17 dpo depending on when I actually ovulated. I feel nauseous, fatigue, and my boobs are swollen, but my tests are still resolutely negative. There might be the faintest line on FRER but I think that's more the indentation line. Then yesterday, so 15/16 dpo I had really light brown spotting and thought AF was here (which would at this point be a relief as at least I'd know where I stand) but still nothing. Could it have been implantation bleeding? But, this late in the day, wouldn't that make another chemical or MC really likely? I can't face going through it again. I'd really appreciate advice or any similar stories - or even success stories of testing positive after 17 dpo... Thanks.
