@Christie ahh I see, sounds silly but thought it wld be another method to find out if i was pregnant as I’m a week late and had a few negative pregnancy tests x
Not sure will help your purpose but just to say I did use them to time trying for a baby and they did help :)
They won’t help in your situation as you have to take them a certain amount of time before you ovulate depending on how long your cycle usually is, but if you used them again next month at the right time they’re very useful. Helped me fall pregnant both times x
You have to do them leading up to ovulation (about 2 weeks before your period is due). They detect the hormone that causes an egg to release, that hormone goes away withing 48 hours so it can't tell you whether you ovulated 2+ weeks ago (when your period is due/overdue)
