AF was here 7/2-7/4 ... We have sex quite often, but one time that stands out was on the 12th I was physically exhausted from working too much the day before so after we did the deed I passed out without ever...cleaning up... For at least a few hours... The next two days I had light spotting sometimes pink sometimes brown; but never a full AF...since then I've been a little dizzy and (tmi) going #2 more often than usual... I haven't said anything to DH cause I don't want to get his hopes up...but could it be implantation bleeding??? And if you think you experienced implantation bleeding how long do you wait to test???
