So this is the first time in a while I haven't done a round of Femara/follicle scans/trigger shots/timed intercourse due to finances this month. So usually I have those things to pinpoint when I'm ovulating. Since I don't have those this month, I used this app and it said I was supposed to ovulate Friday. My body is usually pretty good at letting me know when that's about to happen but with the chaos of Hurricane Harvey, I just completely forgot. Now that things have settled down I decided to check out of curiosity. The ovulation sticks shown I did within seconds of each other from the same sample, but they all came out kind of differently. Is it possible that maybe the app and/or my body is off a bit and that first one is showing me I'm ovulating? If so, why do the others not look like it? This is my first time actually using these things so I'm not really sure what I'm looking at. If anyone can help, I'd be oh so grateful!
