To be honest foot I'm only going on OPKs as I have never temped. I am lucky to get a reliably positive OPK test at the right time each month, accompanied by lots of ovulation pain niggles, so I'm pretty sure it's happening. No hint of a flipping BFP though for over 9 months now 
You guys are probably still too early to have any symptoms. From how I understand it, up until HSG starts being produced post implantation, you will feel the same - pregnant or not pregnant. Progesterone floods your body after ovulation either way. If eggo gets lucky then progesterone keeps going up and up. If she doesn't meet her match, she dies and progesterone falls away, you get your period. I've found I can tell when the progesterone drops - I start feeling more normal, less hormonally mental, boob pain goes etc.
BFP defo due on this thread this month I reckon...
