Hello again! I have heard of some people using opk as hpt and know that it's not as reliable as taking an hpt. but my question is can you have a neg opk(stark white) at 12do and still end up getting a bfp on a hpt? the wait is KILLING me. i am holding on to some hope, but still don't feel preg. just pms! so I am not going to buy an HPT until after i'm late, couldnt resist trying the OPK but felt disappointed when it came out stark white Thanks!
