I am not entirely certain if ovulation trackers are the same as ovulation predictor kits. If they are, then it is not positive until the test line is as dark or darker then the control line, in which case you are not quite ready to ovulate yet. I can tell you that ovulation predictor kits have worked very well for me. As for invitro, it's a bit early to try that yet I would think. I am a bit surprised he would advise that so quickly. Usually they wait at least 6 months. But yes, with invitro multiples is possible, in fact a close friend of mine had a beautiful set of twins that way. In any event, welcome, and I wish you luck!!!
I have read many women that have tried this brand and didn't get good results. The had way too many positives or no positives at all. Some were using this and another OPK and these showed nothing while the other brand showed a definite +. To each his own but I would try another brand. Ask around here to find out what people like best. Some people really like the one that gives you a definitive smiley face because there is no guessing but they are expensive. Clear blue easy work well but again, you are diferentiating between lines and trying to determine if they are the same or darker......
I use the clear blue fertility monitor. The monitor is a bit pricey but it is very accurate. It tells you when your fertility is low, high, and peak. High and peak fertility days are when you want to BD. It can give you up to 5 fertile days instead of one or two.
Thanks so much cmoretti for the info becassue the test have been coming positive all week and I was a little concerned about that. So i am definitly going to go get a better different brand.
