I'm currently about 9/10 DPO. I've been having positive OPK the past 2 days but negative pregnancy tests. Is it possible that I've been testing too early or should test really be showing positive by now if the OPKs are positive. I've never had positive OPK this late in my cycle apart from time of ovulation and been tracking for 8 months now. I also have zero symptoms of PMS which I'd usually have, generally I'd be irritable, fatigued and have acne at this time but I'm complete opposite full of energy, calm and clear skin but I'm starving all time!
