Also having a positive OPK at totally the wrong time..but all negative on HPTs....all this OPK business has got me very confused! So your test is getting darker again...hmm, do you think you definitely ovulated the first time around? have you taken a HPT? I wish I could offer advice or even experience, but I really can't and wish someone would answer my questions!! Like, some people say there's a surge of LH just before your period- but nothing confirms this (well, a very slight raise in LH but not one that should produce a dark, positive OPK anyway) so..I don't know where this idea came from...It's going around all the pregnancy forums (babycentre, baby and bump, netmums etcetcetc..) but nothing scientific or solid about this. Also, getting positives when nothing else matches...what does that mean??
