I need some help! I've been trying to chart my ovulation I've been using 2 different OPKs The clearblue advanced ovulation kit and then the Answer ovulation kit. For the past 3 days I've used my FMU for the CB kit got 2 negative answers Saturday & Sunday then a solid smile this morning which according to the directions means I've hit peak fertility mind you this is the second solid smiley face I've gotten this cycle, anyway with the Answer kit every time I've tested the line has always been very faint which means I'm not ovulating! Im very confused as to what's going on! Ive just started on PN vitamins would that effect the test??? Please help
