im VERY new to using these they look like IC pregnancy test but blue handle anyway whats peoples experience with them? i just did one and control line is dark but faint if that makes any sence? and another line is faint but thick and there. reading packet says anything lighter than control line is a negative... but to get a faint line could it mean im coming up to ovulation? they said in listing there very sensative and even says 10 miu on packet which i wasnt sure ovulation test said that?
