Me and my husband are trying to conceive our first baby. I came off the pill in preparation in July last year and we started actively trying at the beginning of May (couldn't try before due to Zika risk). I track my periods (29 day cycle) on the flo app which predicts ovulation. Due to not being successful so far we decided to use ovulation sticks this month to give a helping hand. My app predicts ovulation on Saturday and I am testing daily, at the moment there is the control line, but no hint of another line. I believe I have read on here that most people have a line and the strength of it increases when they ovulate? I'm aware that the app may be wrong but I'm worried I'm not ovulating at all. I'm a healthy weight but do a lot of exercise (I do not want to change this unless absolutely necessary).
Can anyone offer any advice as to whether the ovulation stick line will develop as hormones increase or if it just appears during a very small window? Any other advice welcome.
